Replace SendKeys approach with respawn-pane -k when starting Claude
in crew sessions. This gives cleaner exit behavior:
- Before: Claude exits → shell prompt → exit shell → session ends
- After: Claude exits → session ends (no intermediate shell)
Changes:
- Add GetPaneID() to tmux package for pane ID retrieval
- Update crew_at.go to use RespawnPane for both new and restart cases
- Remove unnecessary waits and multi-step Claude startup
