feat: Create crew agent beads in doctor --fix and crew add

- doctor/agent_beads_check.go: Check and create agent beads for all crew workers
  - New listCrewWorkers() helper finds crew directories in each rig
  - Run() checks for missing crew agent beads
  - Fix() creates missing crew agent beads with proper fields

- cmd/crew_add.go: Create agent bead when adding a crew worker
  - Creates gt-crew-<rig>-<name> agent bead after workspace creation
  - Non-fatal if bead creation fails (warns but continues)
