[himattm]

Summary

Bump version from 0.2.0b1 to 0.2.0 for stable release.

Changelog (0.1.4 → 0.2.0)

Fixed

• Orphaned task cleanup with PID reuse detection - Tasks from cancelled sub-agents no longer block subsequent tasks (Refactor queue core and fix orphaned task cleanup #7)

  • Added is_task_queue_process() to detect if a PID is actually running task_queue vs being reused by an unrelated process
  • Added SERVER_INSTANCE_ID and _active_task_ids tracking in MCP server to detect orphaned tasks from disconnected clients
  • Added CLI_INSTANCE_ID tracking in tq.py for same protection
  • Handle asyncio.CancelledError to properly clean up when sub-agents are cancelled
