When gt spawn creates a polecat, it now sends POLECAT_STARTED notifications
to both Witness and Deacon:
- Witness receives: "POLECAT_STARTED <polecat>" with issue and session info
- Deacon receives: "POLECAT_STARTED <rig>/<polecat>" with issue and session info
This enables:
- Witness to bond a lease to its patrol wisp
- Deacon to verify worker started (redundancy)
- Both to nudge if worker is idle at prompt
