pingqiuandClaude Opus 4.6 e200df7791 feat: Task I — recovery execution helpers extracted to sw-block runtime
New reusable execution helpers in sw-block/engine/replication/runtime:
- ExecuteCatchUpPlan: drives catch-up execution, notifies host via callback
- ExecuteRebuildPlan: drives rebuild execution, notifies host via callback
- RecoveryCallbacks interface: host-side OnCatchUpCompleted/OnRebuildCompleted

The host (weed/server/block_recovery.go) supplies concrete IO bindings and
receives completion notifications. The reusable execution logic no longer
requires weed/server ownership.

4 tests prove boundary behavior:
- catch-up callback receives achievedLSN matching plan target
- catch-up with plan-derived target works correctly
- rebuild callback receives plan reference
- nil callbacks don't panic

weed/server rebinding to use these helpers deferred to Task J
(legacy isolation).

pingqiuandClaude Opus 4.6 6fea93e821 feat: Task H — PendingCoordinator extracted to sw-block/engine/replication/runtime
New reusable pending-execution coordinator with fail-closed command matching:
- Store/TakeCatchUp/TakeRebuild/Cancel/Has/Peek
- TakeCatchUp: fail-closed on target LSN mismatch (cancel + return nil)
- TakeRebuild: same fail-closed semantics
- Cancel callback invoked on mismatch or explicit cancellation

9 tests prove boundary behavior:
- match succeeds, mismatch cancels, explicit cancel, noop on empty,
  peek non-destructive, store replaces, take from empty

No weed/ imports. Pure coordination logic reusable by any adapter shell.
weed/server/block_recovery.go rebinding deferred to Task I.
