test(web): pin every scenario end-state with an aria golden

Every spec now commits at least one golden and the interactive ones one
per distinct end-state (nine new .expected.md):

- live-interactions: cancel.expected.md (frozen partial + 已停止 marker),
  error-auth.expected.md (the prompt bubble alone — the committed artifact
  of the web-error-surface gap, the diff that flips when error rendering
  lands), retry.expected.md (indistinguishable from a clean completion —
  retries are deliberately invisible in the transcript).
- question-composer: answered.expected.md (the question resolved into its
  tool round trip plus the final reply, takeover gone) beside the existing
  waiting-state golden.
- steering: mid-steer.expected.md pins the accepted-but-INVISIBLE state
  (the loop drains steering only at the step boundary, so no interjection
  bubble exists while the question still blocks — if the client ever
  renders pending steers eagerly, this golden flips first) and
  settled.expected.md the badged bubble plus obeying reply.
- navigation-panes: waterfall.expected.md and details-open.expected.md
  (tool-name header, Input args, Output result) beside the trajectory one.
- lifecycle-chrome: reloaded.expected.md — rendering the same settled
  transcript from persistence alone IS the recovery claim.

Fixture inventories extended to the new closed sets; the Agent Note's
expected-outputs policy updated in both languages (per-end-state goldens
for interactive scenarios), pairing re-recorded.
