test(live): answer the Current Debate prompt and pin Muse Spark 1.3 Contributor

The live journeys were never updated for Current Debate (#72): Actions was
out of minutes from 2026-09-27 to 2026-09-30, so the first real live-e2e run
was on 2026-10-01. Five journeys stopped at "Which debate is this for?" or,
in the Library, at a disabled Add Source button with no current debate. They
now answer the prompt the way the full-stack specs do, and the Library
journey starts a debate first.

The live gate's default model is now meta/muse-spark-1.3-contributor
($0.10/$0.20 per million tokens, against $0.15/$0.50 for GLM 5.3 Flash). It
supports every parameter the app sends. It is test-only and stays out of the
app catalog.

-Live mode uses the same locked stack but skips pgTAP and the fake-provider specs. It runs `e2e/live/` on desktop Chromium against real OpenRouter, Jev, and Exa. Imported web pages are fetched live too. The fake provider becomes a recording proxy. It forwards every chat call to OpenRouter with the model pinned to `LIVE_MODEL` (default `z-ai/glm-5.3-flash`; CI reads the `LIVE_MODEL` repository variable), passes Jev decisions through unchanged, and refuses calls past `MAX_UPSTREAM_CALLS` (200). The default is inexpensive and broadly hosted, so requests can use OpenRouter's balanced provider routing instead of depending on one endpoint.
+Live mode uses the same locked stack but skips pgTAP and the fake-provider specs. It runs `e2e/live/` on desktop Chromium against real OpenRouter, Jev, and Exa. Imported web pages are fetched live too. The fake provider becomes a recording proxy. It forwards every chat call to OpenRouter with the model pinned to `LIVE_MODEL` (default `meta/muse-spark-1.3-contributor`; CI reads the `LIVE_MODEL` repository variable, which is unset), passes Jev decisions through unchanged, and refuses calls past `MAX_UPSTREAM_CALLS` (200). The default is the cheapest model that supports every request parameter the app sends, including `response_format` and reasoning effort. It is test-only and not in the app catalog, so users cannot pick it. Meta is its only provider, so an outage there fails the gate instead of failing over.
 
 The specs cover web-researched case generation, verified Factoids citations, Ask with web search, URL import, streamed Ask, Attack, Brainstorm, a judged sparring round, and Crossfire with live Jev signals. Outputs vary, so tests assert structure rather than text:
