Fusion Agent c91e5ce42d FN-106: prevent workspace finalization livelock

Repair workspace merge-boundary finalization so empty repository sets cannot loop indefinitely.

- Track workspace merge readiness and durable per-repository obligations.
- Gate landing and recovery on scope, blockers, leases, and checkout ownership.
- Preserve remediation state, add recovery paths, documentation, and regression coverage.
