- packages/llm: add FallbackLLMProvider (providers/fallback.ts) that
tries each provider in order, skipping unconfigured or erroring ones;
wire 'fallback' as a first-class LLMProviderType in factory + types
- packages/llm: improve auto-detection in factory — PERPLEXITY_API_KEY
and GEMINI_API_KEY trigger auto-selection when no explicit provider set
- scripts/release.sh: new pipeline — rebase from origin/main, build,
apply changesets, publish outdated packages to Gitea registry, push
- scripts/run-registry-tests.sh: fix Gitea URL health-check to use a
real package endpoint with auth header instead of bare registry root
- docs: mark Vercel track-B prompts B1–B3 as complete
