feat: Phase 16M/17 + promote fixes + testrunner updates

Phase 16M: explicit replica readiness on heartbeat seam
- master.proto: optional bool replica_ready = 19 (proto regenerated on M01)
- block_heartbeat_proto.go: write/read ReplicaReady with presence semantics
- master_block_registry.go: replicaReadyObservedFromHeartbeat prefers
  explicit proto field, falls back to address heuristic when absent
- volume_server_block.go: heartbeat emits ReplicaReady from core projection

Phase 17: host effects extraction + stop line
- phase-17-log.md: Batch 10/11 delivery notes

Promote fixes:
- master_block_failover.go: deterministic replica addrs from path hash
- qa_promote_replication_test.go: address-upgrade trigger test
- qa_promote_rejoin_live_test.go: new live rejoin test

Testrunner:
- devops.go: action improvements
- recovery-baseline-failover.yaml, suite-ha-failover.yaml: scenario updates
- cp11b3-manual-promote.yaml: promote scenario alignment
- fresh_volume_write_test.go: new component test
