Show elapsed Gemini watch time and refresh-safe progress messaging in Studio

[Copilot]

Canonical issue

Handled by system issue-link automation.

Outcome

Studio now surfaces a live elapsed timer for long Gemini transcription runs and explicitly tells users the pipeline continues after a page refresh.

Scope

• Included:
  • Progress status copy update: working-state banner now appends refresh-continuation messaging.
  • Transcript stage UI update: while transcript is in-flight, UI now renders a dedicated elapsed line (Gemini watch time: {elapsed}s elapsed.).
  • Regression test: added a focused component test that asserts:
    • initial elapsed render at 0s
    • elapsed increments under fake timers
    • refresh-continuation copy is present
  • Example snippet:

    {transcriptWorking && !selected?.transcript && (
      <>
        <p className="font-mono text-[11px] text-white/40">
          {studioTranscriptEtaLabel(elapsed)}
        </p>
        <p className="font-mono text-[11px] text-white/40">
          Gemini watch time: {elapsed}s elapsed.
        </p>
      </>
    )}

• Explicitly excluded:
  • Pipeline/runtime behavior changes
  • Backend API/protocol changes
  • Deploy/G.A.T.E. flow changes

Risk

• Risk level: low
• Failure mode: UI copy/timer regression in transcript-progress rendering.
• Rollback: revert OneLoopStudio.tsx and the added test block in OneLoopStudio.gate.test.tsx.
