Replace polecat state.json with beads assignee field for state management:
- Remove state.json read/write from polecat.Manager
- Add loadFromBeads() to derive state from issue.assignee field
- Update AssignIssue() to set issue.assignee in beads
- Update ClearIssue() to clear assignee from beads
- Update SetState() to work with beads or gracefully degrade
- Add ListByAssignee and GetAssignedIssue to beads package
- Update spawn to create beads issues for free-form tasks
- Update tests for new beads-based architecture
State derivation:
- Polecat exists: worktree directory exists
- Polecat assigned: issue.assignee = 'rig/polecatName'
- Polecat working: issue.status = open/in_progress
- Polecat done: issue.status = closed or no assignee

This implements the ephemeral polecat model where polecats are spawned
fresh for each task and deleted upon completion.
Key changes:
**Spawn (internal/cmd/spawn.go):**
- Always create fresh worktree from main branch
- Run bd init in new worktree to initialize beads
- Remove --create flag (now implicit)
- Replace stale polecats with fresh worktrees
**Handoff (internal/cmd/handoff.go):**
- Add rig/polecat detection from environment and tmux session
- Send shutdown requests to correct witness (rig/witness)
- Include polecat name in lifecycle request body
**Witness (internal/witness/manager.go):**
- Add mail checking in monitoring loop
- Process LIFECYCLE shutdown requests
- Implement full cleanup sequence:
- Kill tmux session
- Remove git worktree
- Delete polecat branch
**Polecat state machine (internal/polecat/types.go):**
- Primary states: working, done, stuck
- Deprecate idle/active (kept for backward compatibility)
- New polecats start in working state
- ClearIssue transitions to done (not idle)
**Polecat commands (internal/cmd/polecat.go):**
- Update list to show "Active Polecats"
- Normalize legacy states for display
- Add deprecation warnings to wake/sleep commands
