fix: consolidate duplicate PubmConfig types and add missing registries field

Remove legacy `src/types/config.ts` and unify on `src/config/types.ts` as the
single source of truth for PubmConfig. Add top-level `registries` field that
was missing from the defineConfig type, and remove duplicate defineConfig from
loader.ts.
