## What changed
- Add the tool call ID to `_meta.callId` for every MCP tool request.
- Rename `features.tool_registry.include_tool_metadata` to
`features.tool_registry.turn_metadata_includes_tool_info` to clarify that the
setting controls authoritative tool information in per-turn metadata.
- Update config parsing, schema generation, and session config locking for the
renamed setting.
## Testing
- Cover `callId` metadata for custom, plugin, and Codex Apps MCP calls.
- Update strict-config, config-loading, feature-config, and config-lock tests for
the renamed setting.
