amosblomqvist e33b83ca2d fix: steer-delivery starvation — continuation coalescing (claimSteers)
The bug (seen live): a teacher that ends every turn with a new pending quiz
keeps the wake pipeline's idle gates permanently closed — the steer sits in
'delivering result' forever while the learner answers check after check.

- claimSteers (server/jobs.ts): the chat-handler claims every queued,
  undelivered steer the instant a client turn wins the turn registry, and
  appends it after the learner's answer — conversion-safe, the answered
  quiz carries its output. Every answer flushes pending steers immediately.
- The pump keeps its post-idle duplicate-guard (re-check steerDelivered
  before firing), so a claim racing the pump converges to exactly one
  delivery either way.
- The stale-job sweep now skips chats with a turn in flight (a healthy but
  slow wake no longer gets falsely re-queued as 'recovering').
- Out-of-lane surgical touch (flagged for master review): the 3-line
  handleChatRequest seam (claim after beginTurn, persist+stream 'outgoing').
- Verified live end-to-end on the stuck session: answering the pending quiz
  fired the steer + wake turn within a second; job flipped done/delivered.
