fix(respawn): wait for idle timeout before triggering cycle

- Fixed respawn controller immediately sending commands when Claude
  becomes idle, which prevented users from typing. Now waits for
  idleTimeoutMs (default 10s) before triggering the respawn cycle.
- Removed Directory field from Session Options modal for cleaner UI
- Compacted CLAUDE.md documentation for better readability
