Running Tests Locally

npm test

This runs `npm run build` and then executes Node's built-in test runner.

To generate coverage:

npm run test:coverage

To update snapshots:

npm run test:update-snapshots

CI Gate (recommended)

undefined

The provided GitHub Actions workflow runs `npm run test:coverage` on Node 18 and 20.

These steps should be required in PR checks to ensure new changes do not regress existing behavior.
