fix: rewrite P2 as one-chain proofs with pin release assertions
Rebuild ONE CHAIN (proven):
assignment → PlanRebuild → RebuildExecutor.Execute()
→ v2bridge TransferFullBase → engine complete → InSync
→ pinner.ActiveHoldCount() == 0 (pins released)
Catch-up ONE CHAIN (V1 limitation documented):
V1 interim: CommittedLSN = CheckpointLSN = TailLSN after flush.
No gap between tail and committed exists. Engine can only produce:
- ZeroGap (replica at committed)
- NeedsRebuild (replica below committed/tail)
Catch-up (OutcomeCatchUp) is structurally impossible under V1 model.
Real WAL scan proven separately (P1). Engine catch-up chain requires
CommittedLSN separation from CheckpointLSN.
Cleanup: CancelPlan → pins released + session invalidated + logged.
Observability: sender_added + session_created + connected + escalated.
