pingqiuandClaude Opus 4.6 785a7d7efd feat: wire real pinner into flusher retention + real WAL scan executor (Phase 07 P1)
Pinner wired to real retention:
- NewPinner calls vol.SetV2RetentionFloor(p.MinWALRetentionFloor)
- Flusher.RetentionFloorFn() / SetRetentionFloorFn() exposed
- SetV2RetentionFloor chains with existing shipper retention floor
- Holds actually prevent WAL reclaim (not just tracked state)

Executor uses real WAL scan:
- BlockVol.ScanWALEntries(fromLSN, callback) wraps wal.ScanFrom
  with real fd, walOffset, checkpointLSN
- Executor.StreamWALEntries uses ScanWALEntries (not stub)
- Reads real WAL entries, tracks highest LSN scanned

CommittedLSN mapping:
- Explicitly documented as interim V1 model (committed = checkpointed)
- Will diverge when V2 distributed commit separates from local flush

Carry-forward:
- TransferSnapshot/TransferFullBase/TruncateWAL: stubs (need extent I/O)
- Control intent from confirmed failover: deferred

Ping QiuandClaude Opus 4.6 4f3edffb0a fix: canonical replica address resolution (CP13-2)
ReplicaReceiver.DataAddr()/CtrlAddr() now return canonical ip:port
instead of raw listener addresses that may be wildcard (:port,
0.0.0.0:port, [::]:port).

New canonicalizeListenerAddr() resolves wildcard IPs using the
provided advertised host (from VS listen address). Falls back to
outbound-IP detection when no advertised host is available.

NewReplicaReceiver accepts optional advertisedHost parameter for
multi-NIC correctness. In production, the assignment path already
provides canonical addresses; this fix ensures test patterns with
:0 bind also produce routable addresses.

7 new tests. TestBug3_ReplicaAddr_MustBeIPPort_WildcardBind flips
from FAIL to PASS.
