test: Phase 122 if-only Normalized emit smoke

Phase 122 P4: Fixtures and smoke tests
- New fixture: phase122_if_only_normalized_emit_min.hako
- Smoke test: phase122_if_only_normalized_emit_vm.sh
- Verifies: module emission + structure verification in dev+strict mode
- Regression check: phase103 fixture still passes
- All tests PASS
