Per-list optional VerifyCommand (list_config.verify_command) runs via
VerifyCommandRunner in the list's working dir right after a successful
merge/continue-merge, before the task is allowed to reach Done. A
non-zero exit or timeout leaves the merge in place but keeps the task
out of Done and reports StatusVerifyFailed with an output excerpt
through MergeResultDto/review_task; no command configured behaves
exactly as before. Merges against the same repo are now serialized
per working dir so a running verify can't be interrupted by a second
merge landing mid-build. Adds the field to the List Settings modal
(en/de localized) and covers success/failure/timeout in
TaskMergeServiceTests + VerifyCommandRunnerTests.
Replaces the direct EF Status write in PlanningMergeOrchestrator with
_state.ApproveReviewAsync, enforcing the TaskStateService invariant as
sole owner of Status writes. Handles the improvement-parent path where
TaskMergeService already approved the parent's own worktree during the
drain (status == Done on entry → still success). If the parent was
concurrently cancelled, the transition guard rejects the approve,
PlanningCompleted is not broadcast, and the cancelled status is
preserved. ApproveReviewAsync now also sets FinishedAt.
