fix: remove config package references from monorepo docs

- Update .cursorrules/monorepo.md to remove 'config' from shared packages list
- Remove generated React Router type files that should not be committed
- Add .react-router/ to .gitignore as per React Router v7 documentation

These generated type files are fully managed by React Router and should
be gitignored according to the official documentation.
