Two fixes in this commit:
1. daemon/lifecycle.go: Fix agent bead ID pattern for GUPP/orphaned work checks
- Wrong: gt-polecat-<rig>-<name> (e.g., gt-polecat-gastown-nux)
- Correct: <prefix>-<rig>-polecat-<name> (e.g., gt-gastown-polecat-nux)
- Use config.GetRigPrefix() instead of hardcoding gt prefix
- Use beads.ParseAgentBeadID() in extractRigFromAgentID
2. beads/beads.go: Fix invalid --add-label flag in bd create calls
- bd create uses --labels, not --add-label
- bd update uses --add-label (unchanged, was correct)
- Fixed Create, CreateWithID, CreateAgentBead, CreateRigBead
