Summary

• Updated util/lint.py and util/lint.ps1 to use uvx instead of uv run for linting tools
• Simplified CI workflow by removing explicit tool installation (uvx handles it)

Changes

• util/lint.py: Changed uv_run() helper to uvx() for black, isort, pylint, flake8, mypy, bandit
• util/lint.ps1: Changed uv run <tool> to uvx <tool> for all linting tools
• .github/workflows/lint.yml: Removed uv pip install for linting tools

Benefits

• No need to manually install linting tools locally
• Tools are auto-downloaded and cached by uvx on first use
• Simpler CI setup with fewer dependencies to manage

Test plan

• Verified uvx black works locally
• Verified uvx isort works locally
• Verified full lint suite runs successfully with uvx
