- Replace LocalShellComponent's one-shot subprocess.run() with a
PersistentShellSession that wraps a long-running bash process per UMO.
cd/export/source now persist naturally within a conversation.
- Support background task execution via nohup.
- Remove unused ToolSessionManager / ToolSessionState (dead code,
never wired to any consumer).
- Fix performance benchmark: separate throughput and memory measurement
so tracemalloc doesn't distort timing (was 7x slower).
- Optimize bool validation in CommandFilter with frozenset + isinstance
short-circuit.
