A member session parked as blocked with focus on a terminal (or runnable, or
vanished) review card kept the dispatcher skipping its runnable work items
forever — the preempt-restore race leaves focus on an already-approved card
and every existing self-heal only recognized the runnable/missing shapes.
claim_runnable_tasks now converges such sessions to idle before the
blocked-skip branch, and the skip log carries focused/focused_phase for
forensics. (OBS-8; production-verified self-heal in the t4 campaign run.)
