test: Phase 117 if-only nested-if call merge parity (VM + LLVM EXE)
Fixture & Smoke tests for nested if-only with call merge verification.
**Fixture**:
- apps/tests/phase117_if_only_nested_if_call_merge_min.hako
- Pattern: nested if (inner: b == 1) inside outer if (a == 1), outer else
- Call merge: f(1), f(2), f(3) results merged to single variable v
- Expected output: 2, 3, 4 (f(x) = x + 1)
**VM Smoke**:
- tools/smokes/v2/profiles/integration/apps/phase117_if_only_nested_if_call_merge_vm.sh
- Execution: NYASH_DISABLE_PLUGINS=1 HAKO_JOINIR_STRICT=1
- Validation: numeric output 3 lines "2\n3\n4"
**LLVM EXE Smoke**:
- tools/smokes/v2/profiles/integration/apps/phase117_if_only_nested_if_call_merge_llvm_exe.sh
- Required plugins: FileBox, MapBox, StringBox, ConsoleBox, IntegerBox
- Validation: numeric output "2\n3\n4" (3 lines)
**Verification**:
✅ VM smoke: PASS
✅ LLVM EXE smoke: PASS
✅ Regression (Phase 116): PASS
