## Summary
- reconcile successful graph-native workflow results with pending task
checklist steps even when review handoff already moved the card into the
merge column
- preserve terminal, paused, and no-redundant-move behavior
- cover the real Compound Engineering post-review-handoff state with a
regression test
## Root cause
Compound Engineering runs `review-handoff` before `merge`. Review
handoff moves the task to `in-review`, which is also the merge column.
`ensureWorkflowMergeBoundaryTask()` returned immediately for cards
already in that column, before projecting successful
`workflowStepResults` onto legacy `Task.steps[]`. The merger then saw
`0/N` and rejected approved work with `task has incomplete steps`.
## Verification
- RED: regression test failed before the fix because `store.updateTask`
was never called
- GREEN: `executor-graph-boundary.test.ts` — 6 passed
- relevant non-PostgreSQL set — 31 passed, 5 PostgreSQL tests explicitly
skipped
- `@fusion/engine` typecheck passed
- changeset format passed
- `git diff --check` passed
## Baseline note
`ce-workflow-step-executor.test.ts` currently has three failures on
clean `origin/main` after FN-8601 foreach-proof hardening. The same
failures reproduce without this patch and are not regressions from this
change.

## Summary by CodeRabbit
* **Bug Fixes**
* Improved reconciliation after review handoff by projecting completed
step results onto the legacy checklist when reaching the merge column.
* Prevented tasks from being marked approved with incomplete step counts
(including “0/N” style states).
* Reduced unnecessary merge failures and deadlock/pause scenarios when
merge-column progress was already recorded.
* **Tests**
* Added coverage for execute-and-merge workflows, ensuring
merge-boundary resolution updates pending steps without moving the task.
