Subject: [PATCH 2/2] Add uv.lock to .gitignore for library projects

- Rename .gitignore to .gitignore.jinja to enable Jinja templating
- Add conditional block: uv.lock is ignored for 'library' projects, not for 'command', 'notebook', or 'custom'
- Add test to verify conditional behavior across project types
