Three bugs were causing orphaned Claude processes to accumulate:
1. TTY comparison in orphan.go checked for "?" but macOS shows "??"
- Orphan cleanup never found anything on macOS
- Changed to check for both "?" and "??"
2. selfKillSession in done.go used basic tmux kill-session
- Claude Code can survive SIGHUP
- Now uses KillSessionWithProcesses for proper cleanup
3. Crew stop commands used basic KillSession
- Same issue as #2
- Updated runCrewRemove, runCrewStop, runCrewStopAll
Root cause of 383 accumulated sessions: every gt done and crew stop
left orphans, and the cleanup never worked on macOS.
