pingqiu c7eb87c587 feat: Phase 09 — V2 execution primitives and production closure ...

Engine execution layer for V2 replication protocol:
- RebuildInstaller: full state handoff (dirty map, WAL, superblock, flusher)
- TruncateToLSN: exact safety predicate (checkpointLSN == truncateLSN),
  ErrTruncationUnsafe escalation to NeedsRebuild
- SyncReceiverProgress: unconditional Store for post-rebuild alignment
- V2StatusSnapshot: CommittedLSN = nextLSN-1 for sync_all

V2 bridge real I/O executors:
- TransferFullBase: TCP streaming + RebuildInstaller + second catch-up
- TransferSnapshot: SHA-256 verified streaming to disk
- TruncateWAL: ErrTruncationUnsafe detection + escalation
- StreamWALEntries: rebuild-mode TCP apply

Engine executor interfaces:
- CatchUpIO.TruncateWAL, RebuildIO.TransferFullBase returns achievedLSN
- CatchUpExecutor truncation-only skip, NeedsRebuild escalation
- RebuildExecutor uses achievedLSN for progress tracking

Design docs reorganized: superseded planning docs removed, protocol
truths and closure map added.
