Steve Yegge 85ec39c487 fix: Add session health monitoring and auto-restart for crashed polecats (gt-i7wcn) ...

This fix addresses the issue where polecat sessions terminate unexpectedly
during work without recovery:

Changes:
- Add `checkPolecatSessionHealth()` to daemon heartbeat loop
  - Proactively validates tmux sessions are alive for polecats
  - Detects crashed polecats that have work-on-hook
  - Auto-restarts crashed polecats with proper environment setup
  - Notifies Witness if restart fails as fallback

- Add polecat support to lifecycle identity mapping
  - `identityToSession()` now handles polecat identities
  - `restartSession()` can restart crashed polecat sessions
  - `identityToStateFile()` handles polecat state files
  - `identityToAgentBeadID()` handles polecat agent beads
  - `identityToBDActor()` handles polecat BD_ACTOR conversion

- Add `gt session check` command for manual health checking
  - Validates tmux sessions exist for all polecats
  - Shows summary of healthy vs not-running sessions
  - Useful for debugging session issues

This provides faster recovery (within heartbeat interval) compared to
waiting for GUPP violation timeout (30 min) or Witness detection.
