* fix: remove cached mcpClient in diagnostic tracking to prevent stale references
Resolves TODO comment about not caching the connected mcpClient since it can change.
Changes:
- Remove cached mcpClient field from DiagnosticTrackingService
- Add currentMcpClients storage to track active clients
- Update beforeFileEdited, getNewDiagnostics, and ensureFileOpened to accept client parameter
- Add backward-compatible methods to maintain existing API
- Update all callers to use new methods
- Add comprehensive test coverage
This prevents using stale MCP client references during reconnections,
making diagnostic tracking more reliable.
