feat: migrate dependency management from Poetry to uv

[doughayden]

What

Migrate the project's dependency management from Poetry to uv for improved performance and faster dependency resolution.

Why

• uv is significantly faster than Poetry for dependency resolution and installation
• Better lock file handling and more reliable dependency resolution
• Improved compatibility with modern Python tooling
• Faster CI/CD builds due to reduced dependency installation time
• Native support for Python version management
• Better integration with modern Python packaging standards

Tasks

• Replace pyproject.toml Poetry-specific configuration with uv equivalents
• Migrate poetry.lock to uv.lock format
• Update all development scripts in scripts/ directory to use uv instead of poetry
• Update GitHub Actions workflows to use uv for dependency installation
• Update documentation in CLAUDE.md and development docs to reflect uv usage
• Update Docker configurations to use uv
• Test semantic-release and poetry-dynamic-versioning compatibility with uv
• Verify all existing commands work with uv equivalents
• Update contribution guidelines if any exist

Breaking Changes

This will require developers to install uv instead of Poetry for local development.

Priority

Medium - Performance improvement that doesn't affect core functionality

Level of Effort
