pingqiuandClaude Opus 4.6 d2d57851b0 feat: rebuild MVP — dual-lane session with bitmap protection ...

Rebuild session protocol implementation for v2-rebuild-mvp-session-protocol.md.

New files:
- rebuild_bitmap.go: RebuildBitmap — session-scoped dense bitset for
  WAL-applied LBA tracking. MarkApplied on local WAL write (not receive).
  ShouldApplyBase returns false for WAL-covered LBAs (WAL always wins).

- rebuild_session.go: RebuildSession — replica-side two-line rebuild.
  WAL lane (ApplyWALEntry) + base lane (ApplyBaseBlock) with bitmap
  conflict resolution. TryComplete requires BOTH base_complete AND
  wal_applied_lsn >= target_lsn. Volume-level control surface:
  StartRebuildSession, ApplyRebuildSessionWALEntry/BaseBlock,
  MarkRebuildSessionBaseComplete, TryCompleteRebuildSession,
  CancelRebuildSession, ActiveRebuildSession.

- rebuild_mvp_test.go: 4 correctness tests — base+WAL converge,
  WAL-applied never overwritten by base, bitmap set on applied not
  received, control surface start/supersede/complete.

- rebuild_transport_test.go: 2 transport-level tests — two-line with
  real WAL shipping, live writes during base copy with bitmap conflict.

Design docs:
- v2-rebuild-mvp-session-protocol.md: MVP spec with message set, apply
  rules, completion/failure/crash rules, test matrix
- v2-sync-recovery-protocol.md: full protocol context (keepup/catchup/
  rebuild unified design, primary decision logic, two-line model)
- v2-session-protocol-shape.md: protocol shape overview

Protocol engine (reference, not production):
- sw-block/protocol/: 7-event engine with ~300 lines, 13 tests

6 rebuild tests pass, all existing component tests pass.
