fix: Remove 'uv run' prefix from CI commands to use system-installed packages

- Changed from 'uv run pytest' to 'pytest' to use --system installed packages
- Changed from 'uv run ruff/black/mypy' to direct commands
- Fixes pytest-cov not being recognized in CI environment
- System packages are already installed via 'uv pip install --system -e .[dev]'
