docs(mesh): Phase 6 live gate PASSED — all 8 legs green, exit gate MET

Records the full live-gate run against master on the docker-dev three-mesh rig.
All 8 legs pass: three isolated 2-node meshes, one Primary per pair (250/240),
deploy sealed acks=6 over per-cluster ClusterClient, telemetry gRPC :4056 up +
reconnect, reconciler own-cluster-scoped, secrets pair-local, split validator
refuses Dps, and per-pair failover with auto-down 1-vs-1 survival (also closes the
deferred Phase 0a gate). Three defects were caught and fixed forward (3a4ed8dd,
792f28ec) — see the live-gate doc's Findings section. Task 9 marked completed.
