feat: add breakpoint-tolerant clock system and refactor GrimPlayer time handling

This commit Implement zero-cost breakpoint-tolerant time tracking. It introduces a new time architecture for GrimPlayer that allows developers to pause execution at breakpoints without triggering Timer, FastBreak, or Velocity violations upon resumption. Changes: - Refactored `GrimPlayer` to use `nano()`/`now()` overrides instead of direct System calls. - Added `DebugGrimPlayer` subclass which uses `ThreadLocal` to track intra-packet execution time. - Logic automatically absorbs execution pauses >200ms (breakpoints) while correctly preserving inter-packet delays (server lag/AFK). - Added `processingPacket()` hooks to the Packet Dispatcher and Tick Manager to manage thread-local timers. - Performance impact is 0 in production due to JIT monomorphic inlining and dead code elimination of the base class methods.

+## Requirements & Installation
+
+- Java 17 or higher. *For more details, see [Updating-to-Java-17](https://github.com/GrimAnticheat/Grim/wiki/Updating-to-Java-17).*
+- A Spigot, Paper, Folia, or Fabric server environment. *For more details, see [Supported-environments](https://github.com/GrimAnticheat/Grim/wiki/Supported-environments).*
+
+If you use a proxy such as Velocity or Bungeecord:
+- If you use Geyser, Floodgate must be installed on the backend server (where Grim is) so Grim can access the Floodgate API.
+- If you use ViaVersion, it must be installed on the backend server (where Grim is) ONLY.
+  Grim does not support having ViaVersion installed on the proxy, even if it is also installed on the backend.

- If you use Geyser, place Floodgate on the backend server so grim can exempt bedrock players. Grim
-  cannot access the Floodgate API if it is on the proxy.
- If you use ViaVersion, it should be on the backend server as movement is highly dependent on
-  client version.

Axionize	4933fd9d4f	feat: add breakpoint-tolerant clock system and refactor GrimPlayer time handling This commit Implement zero-cost breakpoint-tolerant time tracking. It introduces a new time architecture for GrimPlayer that allows developers to pause execution at breakpoints without triggering Timer, FastBreak, or Velocity violations upon resumption. Changes: - Refactored `GrimPlayer` to use `nano()`/`now()` overrides instead of direct System calls. - Added `DebugGrimPlayer` subclass which uses `ThreadLocal` to track intra-packet execution time. - Logic automatically absorbs execution pauses >200ms (breakpoints) while correctly preserving inter-packet delays (server lag/AFK). - Added `processingPacket()` hooks to the Packet Dispatcher and Tick Manager to manage thread-local timers. - Performance impact is 0 in production due to JIT monomorphic inlining and dead code elimination of the base class methods.	2025-11-27 20:23:11 -05:00
