Expected Output

Lint/typecheck should exit with:

• Exit code 0 = No issues
• Exit code 1 = Issues found

Integration with Self-Test

After implementing code:

1. Run lint: bunx biome check . (or uv run ruff check .)
2. If issues → fix them
3. Run typecheck: bunx tsc --noEmit (or uv run mypy src/)
4. If type errors → fix them
5. Continue to tests
