Validate Before Commit

Do not declare a task done until the full validation sequence has passed. Run these checks proactively — do not wait for the human to ask.

Standard sequence

# 1. Linting, formatting, and basic static checks
uv run pre-commit run --all-files

# 2. Type checking
uv run mypy <package_or_src_dir>

# 3. Infrastructure plan (if Pulumi files were changed)
pulumi preview --stack <stack-name>
