Tianyi Cui 04b7f517ae test(web): live-turn interaction scenarios — cancel, error, retry, question composer, steering
Five browser e2e scenarios over the existing keyless lane, one recorded
base fixture per spec family:

- live-interactions: one tool-free recorded turn + per-run override
  sidecars authored in the spec (content single-sourced from the fixture
  via deriveReplayScript, minted into a spec-owned temp dir). Cancel uses
  a hang patch with a readyFile marker — the marker proves the stream is
  parked mid-turn before the Stop click, so mid-stream cancellation is
  deterministic by construction (turn/end 'aborted', composer re-enabled).
  AUTH pins the non-retryable path: turn/end 'error', zero llm/retry
  events, composer recovers; FIXME(web-error-surface) marks the found
  product gap (no error copy renders — the client consumes no agent/error
  frames and a pre-chunk failure freezes no partial). SERVER retry appends
  the fixture's own success after an injected throw and proves llm-retry
  end-to-end in the browser via the durable llm/retry record.
- question-composer: the shipped ask_user_question takeover blocks the
  turn mid-step on the real userInteraction seam; the test answers through
  the composer (the one sanctioned model-content-reactive drive step: the
  turn cannot complete without it) and the tool result carries the answer.
  Adds the composer waiting-state aria golden.
- steering: steers mid-turn while the composer blocks the step (the
  deterministic mid-turn window). The steer rides the real wire
  (session.prompt mode:'steer' POSTed from the page; the locked composer
  has no steering gesture yet — TODO(web-steer-composer)); downstream is
  all product: gateway -> Agent.steer -> step-boundary drain -> durable
  steering/message -> SSE -> badged interjection bubble. Record mode
  rejects a fixture whose live reply ignored the steer.

Scaffold gains the replayOverride passthrough; specs register in both
tsconfig planes (client exclude, host include).
