### Description
We are adding support for the Connection Status command, which exists in native Mongo, and allows users to see their authenticated user, authenticated roles, and user privileges. For more information, visit connectionStatus.md.
This PR is the second of three PRs for this feature. The first one added extensible role privileges to our `users_info` command, allowing users to retrieve role privileges with `showPrivileges: true`. This second PR adds a callable `connection_status` command to our API, that utilizes the role privileges. The last PR will add a gateway change that calls this `connection_status` command.

Enhancement and bug fix to improve the stability and management of file-based cursors.
#### PR Summary
This pull request refactors and bolsters file-based cursor management by introducing shared memory support, improved cleanup, error handling, and configuration changes. It also adds new API endpoints and logging for better cursor lifecycle control.
- **`cursor_store.c` and related files:** Added shared memory functions (e.g., `FileCursorShmemSize`, `InitializeFileCursorShmem`), cursor count regulation (with `IncrementCursorCount`/`DecrementCursorCount`), and cleanup routines to ensure stable cursor file operations.
- **Test and expected output files:** Updated regression tests and expected outputs to cover scenarios like duplicate cursor creation, cursor deletion limits, and error reporting when the file cursor capacity is reached.
- **API enhancements:** Introduced new UDFs (e.g., `command_delete_cursors`) and tenant client methods for killing and deleting cursors, improving session management.
- **Configuration updates:** Renamed and added GUC parameters (e.g., `MaxAllowedCursorIntermediateFileSizeMB`, `MaxCursorFileCount`, and cursor expiry settings) to control file-based cursor behavior.
- **Logging and metrics improvements:** Enhanced logging in `mdsd_logger.c` to report current cursor counts and related metrics for operational insight.

#### PR Classification
This pull request delivers a new feature and API enhancement to enable order-by index pushdown and refined composite index support.
#### PR Summary
The update streamlines composite index processing by introducing stricter equivalency checks, new UDF functions for full-scan order-by pushdown, and enhanced validations during index creation while updating explain outputs and tests.
- `src/metadata/index.c` refines index options equivalency logic to correctly compare composite term settings.
- `src/opclass/bson_gin_composite_entrypoint.c` and `src/index_am/rum.c` add functions to support order-by pushdown and manage duplicate entries efficiently.
- `sql/udfs/query/bson_dollar_comparison--0.105-0.sql` (and related operator files) introduce new UDFs including `bson_dollar_fullscan` to enable full scan operations.
- `src/commands/create_indexes.c` enforces new composite index validations (restricting use to ascending, non-wildcard regular indexes) with precise error reporting.
- Test scripts and explain plan outputs in the `regress` and `pgmongo` directories are updated to confirm the new composite order-by behavior.

### Description
Today, persisted cursors require the connections to be held. This is bad since Connections/Backends are a limited resource.
This introduces the option to save the cursor state in a file on disk and reuse that across backends.
This is behind a GUC due to the presence of the following:
1) Needs more testing and validation
2) Needs backpressure to ensure that disk consumption doesn't balloon up
3) There is a procedure added to clean up these files but it is not wired up
4) We need to handle ultra-large responses (beyond 4 GB it fails outright at the moment). This needs more graceful handling to split into chunks.
----
#### AI description (iteration 1)
#### PR Classification
This pull request is a new feature implementation that introduces file‐based persisted cursors to allow query results to be “drained” and stored on disk without holding on to active database connections.
#### PR Summary
This PR adds support for persisting cursor state to the filesystem in both the pg_documentdb and pgmongo modules, enabling connections to be released while still allowing cursors to be later resumed. The changes include:
- **`infrastructure/cursor_store.c` and `cursor_store.h`** – New APIs for creating, writing to, reading from, and closing persisted cursor files.
- **Commands integration** – Modifications in `commands/cursors.c`, `commands/aggregation_commands.c`, and `cursor_private.h` to use file-based cursor functions for draining and continuation.
- **SQL test suites** – Addition of new test files (e.g. in `.../regress/sql/bson_aggregation_cursor_tests_file.sql`) to validate cursor behavior across various query scenarios.
- **Configuration updates** – New custom GUCs in `feature_flag_configs.c` and adjustments in test PostgreSQL configuration files to enable and control file-based persisted cursors.
- **Executor enhancements** – Updates in cursor draining and query plan execution functions to support both in-memory and file-based cursor paging.

Bugfix to override nested arrays in dotted path in `bson_dollar_merge_documents` UDF for few cases
### Description
bson_dollar_merge_documents function today recurses into nested arrays always and project in each element of array but that is not correct with mongo semantics.
This is only applicable if the projectetion is a dotted path.
The function is used in 7 different stages/features today:
1- list_collection: no dotted paths for projection, so this is okay to follow any projection.
2- graphlookup: Mongo does a shallow projection in this case.
3- lookup: Mongo does a shallow projection in this case.
4- inverseMatch: okay as no dotted path projection
5- count: okay as no dotted path projection
6- group : okay as no dotted paths are allowed
7- setWindowFields: only this stage does a full projection even inside nested arrays

Currently bulk insert run as a function which means that the entire execution runs as a single transaction. Each batch insert is handled as a subtransaction and rolled back to a save point if it fails.
This means that document locks are held for longer, and we can hit limits w.r.t. max documents updated per transaction.
In multi-node setups this also means distributed transactions are held longer causing loss of connection pools.
This change introduces a stored procedure for bulk insert that periodically "Commits" the state to WAL and starts a new transaction. This more mirrors what the non-atomic bulk update is supposed to do. The old function is retained to be used within transactions.
