Steve Yegge 6cfab58e86 feat(witness): Implement Witness MVP for automated polecat lifecycle
Implements the core Witness functionality:

- gt witness start: Creates tmux session with Claude, theming, auto-priming
- gt witness stop: Kills tmux session and updates state
- gt witness status: Shows session state reconciled with tmux
- Shutdown handler: Verifies git clean state before cleanup, sends nudges
- Auto-spawn: Spawns polecats for ready work up to configurable capacity
- Health checks: Monitors polecat activity, nudges stuck workers, escalates

Also updates handoff to include polecat name in lifecycle requests.

Closes: gt-53w6, gt-mxyj, gt-5wtw, gt-cpm2, gt-es1i
