gsxdsm 9f45f108e5 FN-7174: reset lost steps before stuck requeue cleanup

Preserve durable stuck-requeue progress while preventing retries from skipping deleted uncommitted work.

- Reconcile completed and in-progress steps before stuck cleanup removes executor worktrees.
- Reset step progress when a branch has no unique commits or git proof fails before checkout deletion.
- Cover normal, loop-timeout, and force stuck-requeue paths with regression tests and documentation.
