- Add getAgentBeadState() and getAgentBeadInfo() to read agent state from beads
- Add identityToAgentBeadID() to map daemon identities to agent bead IDs
- Update ensureDeaconRunning() to check agent bead state first (ZFC compliant)
- Add agent bead state logging in executeLifecycleAction()
This is the first step toward ZFC-compliant state detection. Dependent tasks:
- gt-psuw7: Remove PID/tmux state inference
- gt-2hzl4: Add timeout fallback for dead agents
