* fix: session lost after evoscientist restart
* feat: Implement memory worker thread deletion on completion
- Added synchronous and asynchronous functions to delete memory worker threads after they finish execution, ensuring no residual checkpoints are left in the database.
- Enhanced `_watch_memory_worker_run_sync` and `_watch_memory_worker_run_async` to invoke deletion functions upon confirming worker completion.
- Introduced tests to verify that worker threads are deleted correctly upon successful completion and that failures in deletion do not affect the overall worker status.
- Updated session management to ensure that only relevant threads are restored from the database, preventing exposure of internal or unrelated workspace threads.
- Implemented a purge function to clean up leftover worker checkpoints during server startup.
* feat: Implement short thread ID display for CLI and session hints
* fix: ensure proper accounting and deletion order for memory worker threads
