Self-contained GitHub OAuth (Arctic) with a stateless HS256 signed-cookie session (jose); Supabase is downgraded to the Postgres host only. - Origin-derived callback (no redirect-uri env); read:user scope; access token read once at callback and discarded (no token storage). - CSRF via single-use state cookie; open-redirect guard on next. - getCurrentGithubIdentity() now reads the session cookie, preserving the numeric provider_id identity contract for admin/dashboard/mint. - Remove @supabase/ssr + @supabase/supabase-js, middleware, and the supabase-dependent rls test; delete lib/supabase clients.
