Update README and add setup, docker, and changelog documentation

Add JDBC-backed activity logging for queue, playback, search, skip, listener, and command events.

Logging is disabled by default and can be enabled with `dblog.enabled=true`. The default JDBC URL uses SQLite via `jdbc:sqlite:musicbot.db`, but other JDBC backends can be configured with the same settings block.

+# Contributor Covenant Code of Conduct
+
+## Our Pledge
+
+In the interest of fostering an open and welcoming environment, we as
+contributors and maintainers pledge to making participation in our project and
+our community a harassment-free experience for everyone, regardless of age, body
+size, disability, ethnicity, sex characteristics, gender identity and expression,
+level of experience, education, socio-economic status, nationality, personal
+appearance, race, religion, or sexual identity and orientation.
+
+## Our Standards
+
+Examples of behavior that contributes to creating a positive environment
+include:
+
+* Using welcoming and inclusive language
+* Being respectful of differing viewpoints and experiences
+* Gracefully accepting constructive criticism
+* Focusing on what is best for the community
+* Showing empathy towards other community members
+
+Examples of unacceptable behavior by participants include:
+
+* The use of sexualized language or imagery and unwelcome sexual attention or
+ advances
+* Trolling, insulting/derogatory comments, and personal or political attacks
+* Public or private harassment
+* Publishing others' private information, such as a physical or electronic
+ address, without explicit permission
+* Other conduct which could reasonably be considered inappropriate in a
+ professional setting
+
+## Our Responsibilities
+
+Project maintainers are responsible for clarifying the standards of acceptable
+behavior and are expected to take appropriate and fair corrective action in
+response to any instances of unacceptable behavior.
+
+Project maintainers have the right and responsibility to remove, edit, or
+reject comments, commits, code, wiki edits, issues, and other contributions
+that are not aligned to this Code of Conduct, or to ban temporarily or
+permanently any contributor for other behaviors that they deem inappropriate,
+threatening, offensive, or harmful.
+
+## Scope
+
+This Code of Conduct applies both within project spaces and in public spaces
+when an individual is representing the project or its community. Examples of
+representing a project or community include using an official project e-mail
+address, posting via an official social media account, or acting as an appointed
+representative at an online or offline event. Representation of a project may be
+further defined and clarified by project maintainers.
+
+## Enforcement
+
+Instances of abusive, harassing, or otherwise unacceptable behavior may be
+reported by contacting the project team at j@gro.sh. All
+complaints will be reviewed and investigated and will result in a response that
+is deemed necessary and appropriate to the circumstances. The project team is
+obligated to maintain confidentiality with regard to the reporter of an incident.
+Further details of specific enforcement policies may be posted separately.
+
+Project maintainers who do not follow or enforce the Code of Conduct in good
+faith may face temporary or permanent repercussions as determined by other
+members of the project's leadership.
+
+## Attribution
+
+This Code of Conduct is adapted from the [Contributor Covenant][homepage], version 1.4,
+available at https://www.contributor-covenant.org/version/1/4/code-of-conduct.html

-
-      "Derivative Works" shall mean any work, whether in Source or Object
-      form, that is based on (or derived from) the Work and for which the
-      editorial revisions, annotations, elaborations, or other modifications

-      or a Contribution incorporated within the Work constitutes direct
-      or contributory patent infringement, then any patent licenses
-      granted to You under this License for that Work shall terminate
-      as of the date such litigation is filed.

-   4. Redistribution. You may reproduce and distribute copies of the
-      Work or Derivative Works thereof in any medium, with or without
-      modifications, and in Source or Object form, provided that You

-          that You distribute, all copyright, patent, trademark, and
-          attribution notices from the Source form of the Work,
-          excluding those notices that do not pertain to any part of
-          the Derivative Works; and
-
-      (d) If the Work includes a "NOTICE" text file as part of its
-          distribution, then any Derivative Works that You distribute must

-          within such NOTICE file, excluding those notices that do not
-          pertain to any part of the Derivative Works, in at least one
-          of the following places: within a NOTICE text file distributed
-          as part of the Derivative Works; within the Source form or
-          documentation, if provided along with the Derivative Works; or,
-          within a display generated by the Derivative Works, if and
-          wherever such third-party notices normally appear. The contents
-          of the NOTICE file are for informational purposes only and

-          notices within Derivative Works that You distribute, alongside
-          or as an addendum to the NOTICE text from the Work, provided
-          that such additional attribution notices cannot be construed
-          as modifying the License.
-
-      You may add Your own copyright statement to Your modifications and
-      may provide additional or different license terms and conditions
-      for use, reproduction, or distribution of Your modifications, or

-      reproduction, and distribution of the Work otherwise complies with
-      the conditions stated in this License.

-   5. Submission of Contributions. Unless You explicitly state otherwise,
-      any Contribution intentionally submitted for inclusion in the Work
-      by You to the Licensor shall be under the terms and conditions of
-      this License, without any additional terms or conditions.
-      Notwithstanding the above, nothing herein shall supersede or modify
-      the terms of any separate license agreement you may have executed
-      with Licensor regarding such Contributions.

-      PARTICULAR PURPOSE. You are solely responsible for determining the
-      appropriateness of using or redistributing the Work and assume any
-      risks associated with Your exercise of permissions under this License.

-      whether in tort (including negligence), contract, or otherwise,
-      unless required by applicable law (such as deliberate and grossly
-      negligent acts) or agreed to in writing, shall any Contributor be
-      liable to You for damages, including any direct, indirect, special,
-      incidental, or consequential damages of any character arising as a

+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,

+
+## Setup Notes
+
+If you only need the essentials:
+
+1. Create a Discord bot and get its token, see [here](https://jmusicbot.com/getting-a-bot-token/).
+2. Enable the `MESSAGE_CONTENT` intent in the Discord Developer Portal [here](https://discord.com/developers/applications) ([Wiki link](https://jda.wiki/using-jda/gateway-intents-and-member-cache-policy/)).
+3. Configure `config.txt`.
+4. Run the jar directly or use Docker.
+
+For the detailed version, see [docs/setup.md](/git/MusicBot/docs/setup.md).
+
+## Docker
+
+A Docker image is published here: [docker.io/chrisb09/jmusicbot](https://hub.docker.com/r/chrisb09/jmusicbot)
+
+For compose examples and deployment notes, see [docs/docker.md](/git/MusicBot/docs/docker.md).
+
+## YouTube Login
+
+This fork supports Google account login for YouTube playback workarounds.
+
+Enable:
+
+```conf
+youtubeoauth2=true
+```
+
+Do not use your main Google account. Use a burner or otherwise disposable account instead.
+
+More details are in [docs/setup.md](/git/MusicBot/docs/setup.md).
+
+If you use PO tokens or visitor data for YouTube, those details are also covered in [docs/setup.md](/git/MusicBot/docs/setup.md).
+
+## DAVE / Voice Encryption
+
+Discord currently requires DAVE for voice on modern API versions. This fork configures `libdave-jvm` during startup and bundles native binaries for common Linux, Windows, and macOS targets.
+
+If you deploy on an unsupported architecture, add the matching native dependency in [pom.xml](/git/MusicBot/pom.xml). You probably need to build the library from source for your architecture, so have fun with that.
+
+## Upstream And Related Work
+
+This fork incorporates ideas and patches related to:
+
+- [PR-1670](https://github.com/jagrosh/MusicBot/pull/1670)
+- [PR-1703](https://github.com/jagrosh/MusicBot/pull/1703)
+- [PR-1772](https://github.com/jagrosh/MusicBot/pull/1772)
+
+If this fork does not fit your needs, another fork you may want to inspect is [SeVile/MusicBot](https://github.com/SeVile/MusicBot).
+
+## Questions And Contributions
+
+If you run into issues, please include:
+
+- the version you are running
+- whether you are using Docker or the jar directly
+- relevant config changes
+- relevant logs
+
+Fork-specific version notes live in [docs/fork-changelog.md](/git/MusicBot/docs/fork-changelog.md), which should help with troubleshooting and migration as the fork evolves.

+# Docker Guide
+
+This fork supports running the bot in Docker, which is usually the easiest deployment path for a server.
+
+## Image
+
+Published image:
+
+- [docker.io/chrisb09/jmusicbot](https://hub.docker.com/r/chrisb09/jmusicbot)
+
+Container build sources:
+
+- [github.com/chrisb09/jmb-container](https://github.com/chrisb09/jmb-container)
+
+## Minimal Compose Example
+
+```yaml
+version: "2.2"
+
+services:
+  jmusicbot:
+    image: chrisb09/jmusicbot:latest
+    container_name: jmusicbot
+    restart: unless-stopped
+    volumes:
+      - ./config:/jmb/config
+```
+
+Replace `./config` with the host path you actually want to use.
+
+## Config Files
+
+Your persistent bot config should live in the mounted config directory. That lets you redeploy containers without losing your bot settings.
+
+Typical things to configure there:
+
+- bot token
+- owner ID
+- prefix
+- YouTube login toggle
+- YouTube PO token and visitor-data values if needed
+- status message toggle
+- analytics logging settings
+
+## Deploy Flow
+
+A typical update flow is:
+
+1. Pull or rebuild the image.
+2. Restart the container.
+3. Check logs for startup errors.
+
+Useful commands:
+
+```bash
+docker-compose up -d
+docker-compose logs -f jmusicbot
+```
+
+## Alpine / musl Note
+
+This fork bundles native support for Alpine-compatible musl environments as part of its DAVE setup, so Alpine-based container deployments are supported.
+
+## SQLite Logging In Docker
+
+If you enable analytics logging with SQLite:
+
+```conf
+dblog.enabled = true
+dblog.jdbc_url = "jdbc:sqlite:musicbot.db"
+```
+
+make sure the database file lives somewhere inside your mounted persistent config or data path if you want it to survive container recreation.
+
+## YouTube Token Notes In Docker
+
+If you use YouTube login or PO token based configuration, keep those values in your persistent mounted config rather than baking them into the image.
+
+Relevant config values include:
+
+```conf
+youtubeoauth2 = true
+ytpotoken = "PO_TOKEN_HERE"
+ytvisitordata = "VISITOR_DATA_HERE"
+```
+
+## Recommendation
+
+For production-style use, Docker is the cleanest path if you want:
+
+- reproducible runtime behavior
+- simple upgrades
+- easier separation between bot code and persistent config

+# Fork Changelog
+
+This file tracks fork-specific changes that are useful to operators and contributors. It is not meant to replace commit history, but to summarize what changed at a higher level.
+
+## 0.6.3
+
+- Added JDBC-backed playback analytics logging.
+- Added SQLite as the default logging backend.
+- Logged queue, playback, listener, search, skip, and command activity.
+- Added `dblog.*` config settings to enable and configure logging.
+
+Config:
+
+```conf
+dblog.enabled = true
+dblog.jdbc_url = "jdbc:sqlite:musicbot.db"
+dblog.user = ""
+dblog.password = ""
+```
+
+By default, logging is disabled.
+
+## 0.6.2
+
+- Fixed several status-message race conditions and repost issues.
+- Added debug logging around status-message creation, editing, deletion, and repost flow.
+- Added a config toggle to disable the status-message feature entirely.
+
+Config:
+
+```conf
+statusmessages = true
+```
+
+Set it to `false` to disable the feature.
+
+## 0.6.1
+
+- Bumped the fork version after the initial status-message work had landed.
+
+## 0.6.0
+
+- Updated the bot for modern JDA and Discord requirements.
+- Added DAVE voice support required for current Discord voice playback.
+- Continued dependency refreshes for lavaplayer and related components.
+- Carried forward work related to YouTube login, PO token handling, and buildability on the newer stack.
+
+Imported work included in this fork:
+
+- PR-1670, support for logging into a YouTube account, is included from `0.4.5` onward.
+- PR-1703, changes to allow building the project from source more easily, is included from `0.4.5` onward.
+- `jagrosh#1772`, YouTube PO token and IP rotation support, is included from `0.4.7` onward.
+
+## Notes
+
+- This fork may move faster than upstream in areas related to Discord API compatibility and deployment practicality.
+- When reporting issues, mention the exact fork version because behavior around playback, status messages, and logging has changed across recent releases.

+# Setup Guide
+
+This guide covers the normal non-Docker setup path and the main configuration points that matter on this fork.
+
+## Prerequisites
+
+- Java 11 or newer
+- A Discord bot token
+- A Discord application with the bot invited to your server
+
+## Discord Setup
+
+1. Create a bot in the [Discord Developer Portal](https://discord.com/developers/applications).
+2. Copy the bot token.
+3. Enable the `MESSAGE_CONTENT` intent.
+
+This intent is required for command-based bots like this one.
+
+## Privileged Intent Notes
+
+This fork moved from JDA 4 to JDA 6, so `MESSAGE_CONTENT` is now an important operational requirement for the classic text-command flow.
+
+Keep in mind:
+
+- If the bot joins more than 100 servers, this intent must be enabled in the [Discord Developer Portal](https://discord.com/developers/applications).
+- `MESSAGE_CONTENT` is a privileged intent.
+- Discord verification requirements become relevant as the bot grows.
+- The related portal controls historically only become visible once the application is already in a fairly large number of servers.
+
+For the broader Discord/JDA behavior, see the [JDA gateway intents documentation](https://jda.wiki/using-jda/gateway-intents-and-member-cache-policy/).
+
+## First Configuration
+
+The bot reads from `config.txt` using the values defined in [reference.conf](/git/MusicBot/src/main/resources/reference.conf).
+
+The minimum settings you should care about first are:
+
+```conf
+token = "YOUR_BOT_TOKEN"
+owner = 123456789012345678
+prefix = "@mention"
+```
+
+Useful fork-specific options:
+
+```conf
+youtubeoauth2 = true
+statusmessages = true
+dblog.enabled = false
+```
+
+You may also need these for YouTube PO token support:
+
+```conf
+ytpotoken = "PO_TOKEN_HERE"
+ytvisitordata = "VISITOR_DATA_HERE"
+```
+
+## Running The Bot
+
+Build:
+
+```bash
+mvn clean package
+```
+
+Run:
+
+```bash
+java -jar target/JMusicBot-*-All.jar
+```
+
+This fork includes changes to keep source builds practical on the newer stack as well.
+
+## YouTube Login
+
+If YouTube playback is unreliable, enable:
+
+```conf
+youtubeoauth2 = true
+```
+
+After startup, the bot prints instructions and sends the owner a DM with the authorization flow.
+
+Important:
+
+- Do not use your main Google account.
+- Use a burner or otherwise disposable account.
+
+If you are starting from a clean config, this option should already exist with a default of `false`.
+
+## YouTube PO Tokens And Visitor Data
+
+This fork also supports explicit YouTube PO token and visitor-data configuration.
+
+Config:
+
+```conf
+ytpotoken = "PO_TOKEN_HERE"
+ytvisitordata = "VISITOR_DATA_HERE"
+```
+
+You can generate these values with:
+
+- [iv-org/youtube-trusted-session-generator](https://github.com/iv-org/youtube-trusted-session-generator)
+
+This is useful when normal YouTube playback is not enough and you need a more explicit trusted-session style setup.
+
+## DAVE / Voice Support
+
+This fork includes DAVE support for current Discord voice requirements. In normal supported environments, nothing extra is required beyond using the provided shaded jar.
+
+If you run on an unsupported architecture, add the correct native `libdave-jvm` dependency in [pom.xml](/git/MusicBot/pom.xml).
+
+Bundled native targets include:
+
+- Linux glibc x86_64
+- Linux musl x86_64
+- Windows x86_64
+- macOS
+
+## Status Messages
+
+The bot can maintain a single playback status message in the active text channel.
+
+Config:
+
+```conf
+statusmessages = true
+```
+
+Disable it with:
+
+```conf
+statusmessages = false
+```
+
+## Analytics Logging
+
+Playback analytics logging is off by default.
+
+Enable SQLite logging:
+
+```conf
+dblog.enabled = true
+dblog.jdbc_url = "jdbc:sqlite:musicbot.db"
+```
+
+This creates a local SQLite database file and records queue, playback, listener, and command activity.
+
+## Windows Note
+
+If you run the bot directly on Windows rather than in Docker, install Java first and consider a service wrapper such as [NSSM](http://nssm.cc/) if you want it to run in the background.
+
+## Related Fork Context
+
+This fork incorporates or builds on work related to:
+
+- [PR-1670](https://github.com/jagrosh/MusicBot/pull/1670) for YouTube account login support
+- [PR-1703](https://github.com/jagrosh/MusicBot/pull/1703) for source builds
+- [PR-1772](https://github.com/jagrosh/MusicBot/pull/1772) for YouTube PO token and IP rotation work
+
+If this fork does not fit your setup, another fork you may want to inspect is [SeVile/MusicBot](https://github.com/SeVile/MusicBot).
