- Update installation instructions in README.md and CLAUDE.md to use uv sync
- Update GitHub Actions workflow to use uv instead of pip
- Add uv.lock file for reproducible dependency resolution
- Update deployment process to use uv build

* Fix PR review issues for uv conversion

- Move pytest and flake8 to development dependencies in pyproject.toml

* Add global flake8 configuration to exclude build directories

- Create .flake8 config file to exclude .venv, build, dist, and *.egg-info
- Set max-line-length to 127 and max-complexity to 10
- Simplify GitHub Actions workflow to use global config instead of command-line flags
- Remove tool.flake8 from pyproject.toml (flake8 doesn't support this format)

* Update lock

* Update GitHub Actions workflows

- Update pull-request.yml to use .python-version file instead of hardcoded version
- Add release.yml workflow for automatic deployment when version changes:
  - Detects version changes by comparing current version to last GitHub release
  - Runs tests before deployment
  - Publishes to PyPI using twine
  - Creates git tags and GitHub releases automatically
