Stale claim_lock/claim_expires/worker_pid fields can leak onto ready tasks when a worker crashes and the task is later manually unblocked (e.g. from 'blocked' back to 'ready' via SQL). The reclaim path only inspects status='running' tasks, so these stale locks are never released and the task is permanently skipped by dispatch. Fix: clear claim_lock/claim_expires/worker_pid on any ready task before the dispatch spawn loop. A task in status='ready' cannot have a live worker by definition, so these fields are always stale.

What does this PR do?
Clear stale claim_lock/claim_expires/worker_pid fields on ready tasks
at the start of each dispatch tick. A task in
readystatus cannot havea live worker — these fields are always stale residue from a previous
crashed or blocked run.
release_stale_claimsonly inspectsrunningtasks, so stale locks were permanently blocking dispatch.
