recover_stalled_head_training_runs and recover_stalled_head_auto_apply_runs
were near-exact copies (coalesce-flip + keep-last-N prune, differing only in
model + two constants). Extract _recover_stalled_runs(model, stall_minutes,
keep_runs, label); the two tasks become thin wrappers. The other two recover
tasks are deliberately NOT folded in (library-audit has no prune tail; backup
uses a single started_at cutoff). test_recover_stalled_head_runs.py covers
both wrappers (stalled→error, fresh survives) — previously untested.
