librechat-data-provider → @hanzochat/data-provider @librechat/data-schemas → @hanzochat/data-schemas @librechat/client → @hanzochat/client (@hanzochat/api already forked; external @librechat/agents fork follows) All imports, package.json names/deps, tsconfig path aliases, jest moduleNameMapper, and rollup/vite build aliases updated. The data-provider react-query subpath resolves via the exports map. Lockfiles regenerated in a follow-on once the canonical package manager is confirmed.
