📝 Update README to reference uv instead of Poetry

Update installation and development instructions in README

Modify documentation to reflect migration from Poetry to UV:
- Change installation command from `poetry add` to `uv add`
- Update development setup instructions with UV-specific commands
- Add link to UV GitHub repository

This aligns documentation with the recent dependency management change.
