Done. I've added TypeScript type-check steps to both CI workflows: (#8)

1. **test-core.yml**: Added a "Type check" step that runs `npm run build` before tests
2. **test-mikroorm-driver.yml**: Added a "Type check MikroORM driver" step that runs `npm run build` on the mikroorm-driver workspace before tests

This ensures TypeScript type errors are caught early in CI before tests run, preventing the issue where tests could pass while type errors exist in the code.
