Subject: [PATCH] test(joinir): Phase 123 normalized semantics smoke (VM)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Adds integration smoke test for Phase 123 normalized semantics lowering.

**New Files**:
- `apps/tests/phase123_if_only_return_literal_min.hako`: Minimal test fixture (output: 7)
- `tools/smokes/v2/profiles/integration/apps/phase123_if_only_normalized_semantics_vm.sh`: Smoke test script

**What's Tested**:
- Return(Integer literal) generates correct output
- Dev+strict mode does not fail (graceful degradation works)

**Test Status**: PASS

**Verification**:
```bash
bash tools/smokes/v2/profiles/integration/apps/phase123_if_only_normalized_semantics_vm.sh
# Result: PASS (output: 7)
```
