pingqiu 92c006eb29 refactor: aggregate bounded multi-replica catch-up conservatively
Track catch-up observations per replica so the volume-level recovery view stays in catching_up until all bounded replicas complete. This preserves the current bounded semantics while removing an overclaim that would block later multi-replica startup ownership work.

pingqiuandClaude Opus 4.6 a6fc8545b9 feat: Phase 14A+14B — V2 core publication ownership + command semantics
14A: Publication as explicit core-owned state
- state.go: PublicationView on VolumeState, explicit gate reasons
- engine.go: mode→readiness→publication chain with named gates
  (awaiting_role_apply, awaiting_shipper_configured, awaiting_barrier_durability)
- projection.go: PublicationProjection carries publication truth
- RF=1/no-replicas → allocated_only (CP13-9 constraint in core)
- phase14_core_test.go: strengthened publication closure + RF=1 proof

14B: Command emission bounded by semantic gap
- engine.go: repeated same-assignment skips redundant commands,
  repeated same-reason BarrierRejected skips duplicate invalidation,
  command-state tracking on VolumeState
- command.go: new command types for bounded emission
- event.go: new boundary events
- phase14_command_test.go: exact command sequences frozen as proofs
  (primary/replica repeated assignment, assignment changed, repeated failure)
- phase14_boundary_test.go: boundary/recovery structural tests

All tests pass in sw-block/engine/replication.
Phase 14 docs updated (14A accepted, 14B active→14C planned).
