feat: separate CI jobs for better visibility

- Split CI into 4 distinct jobs: Unit Tests, Prolog Tests, Examples, Benchmarks
- Each job now shows as separate lane in GitHub Actions
- Unit Tests still run on both Node 20.x and 22.x (2 lanes)
- Prolog Tests now visible as dedicated job
- Examples and Benchmarks checks also separate
- Total: 5 CI lanes (Unit 20.x, Unit 22.x, Prolog, Examples, Benchmarks)
