FN-5901: reap stale mission validator runs
Add self-healing recovery for stale mission validator runs left behind after execution ownership disappears.
- add mission-store support to find and reap stale running validator runs, preserving terminal error status and resetting eligible features to needs_fix
- teach the mission execution loop and self-healing maintenance sweep to skip live validations, reap abandoned runs, record audit events, and avoid double-completing runs
- extend regression coverage, mission docs, architecture notes, and add a published-package changeset for the new recovery behavior
