nyash-codex 1a1d223749 feat(phase33): loopform.hako complete implementation - All Stages (1-4) finished
Phase v2-B loopform.hako 完全実装:

【実装】
- loopform.hako (258行): 6-block LoopForm 完全実装
  - Header PHI: incoming 配列 + computed フラグ
  - Dispatch PHI (tag/payload): break/continue 処理
  - Condition: MIR/Payload/Guard 全モード対応
  - Safepoint: GC 安全点統合
- builder.hako (392行): 9 LLVM instructions 統合
- instructions/*.hako (9ファイル): 全命令実装

【テスト】
- Unit test: test_basic.hako (4 tests, 159行)
- Smoke tests (3本, 130行):
  - while_simple.hako: 基本 while ループ
  - for_counter.hako: payload mode カウンタ
  - if_loop_merge.hako: 複合制御フロー + guard

【進捗】
- Stage 1: スケルトン実装 
- Stage 2: PHI incoming 配列化 
- Stage 3: Safepoint & Condition  (Stage 1に含む)
- Stage 4: スモークテスト3本 

【成果】
- 実装: 258行 (Python 224行 + 機能拡張)
- テスト: 289行 (unit 159行 + smoke 130行)
- ビルド: 成功 (0 errors)

次: Phase v2-C MIR Call 統合 + C++ backend 実装

// LoopForm Smoke Test 3: if-else + loop + merge
// Tests complex control flow with loopform
//
// Expected behavior (when C++ backend implements loopform):
// - Conditional branch before loop
// - Loop with early exit (break)
// - Merge point after loop
// - Return merged result
