🔧 chore: standardize on uv for dependency management

Update all documentation and scripts to use `uv` instead of `pip` for installing dependencies. This provides significant performance improvements and better dependency resolution.

Changes:
- Update CLAUDE.md local development setup instructions
- Update README.md installation steps
- Update DEVELOPMENT.md dependency installation
- Update CONTRIBUTING.md setup instructions
- Update vagrant/provision.sh to use uv
- Add uv 0.9.18 to .tool-versions

Note: Dockerfile and GitHub Actions workflows already use uv.
