The documented chains were missing entries and had wrong providers:
- Librarian was missing openai/gpt-5.4-mini-fast, vercel/minimax-m2.7-highspeed,
and the last two entries. Also had opencode/ instead of vercel/ for
minimax-m2.7-highspeed.
- Explore had github-copilot|xai/grok-code-fast-1 as primary (which doesn't
exist in the fallback chain) and was missing openai/gpt-5.4-mini-fast.
Both now match the exact runtime chains from model-requirements.ts.
