13f21334c9 fix(aot): resolve copy chains in PHI propagation for deep loop coverage
Fix CollectionsHot type_table to resolve copy chains when propagating types
through PHI nodes, enabling ArrayBox optimization in deeply nested loops (matmul).

**Root Cause:**
- PHI incoming values were checked directly in type_table
- Copy chains (e.g., SSA 56→11) were not resolved
- Types failed to propagate through deep loop nesting

**Solution:**
- Add copy_src_map parameter to build_type_table()
- Resolve copy chains before checking if PHI incoming values are typed
- Multi-pass fixpoint algorithm (up to 12 passes) ensures convergence

**Impact:**
- matmul: ArrayBox A/B/C now propagate through nested loops
- Expected: boxcall→externcall conversion for get/set/push
- Backwards compatible: opt-in (NYASH_AOT_COLLECTIONS_HOT=1), no behavior change when disabled

**Analysis:**
- Documented in docs/development/analysis/matmul_collections_hot_fix.md
- Box→SSA flow traced: A(dst=2)→...→71(get), B(dst=3)→...→73(get), C(dst=4)→...→105(set)

**Testing:** Pending verification due to VM step budget constraints

52b62c5772 feat(phase21.5): Stage-B parser loop fix + delegate path stabilization
## 修正内容

### 1. Stage-B パーサー修正(偶然の回避)
- **ファイル**:
  - `lang/src/compiler/parser/expr/parser_expr_box.hako`
  - `lang/src/compiler/parser/stmt/parser_control_box.hako`
- **問題**: ネストループで gpos が正しく進まず、loop の cond/body が壊れる
- **回避策**: new 式のメソッドチェーン処理追加で別ループを導入
- **結果**: MIR 生成が変わって VM gpos バグを回避

### 2. delegate パス動作確認
- **テスト**: `/tmp/loop_min.hako` → rc=10 
- **MIR構造**: 正しい PHI/compare/binop を生成
- **チェーン**: hakorune parser → Rust delegate → LLVM EXE 完動

### 3. ドキュメント追加
- `docs/development/analysis/` - delegate 分析
- `docs/development/guides/` - ループテストガイド
- `docs/development/testing/` - Stage-B 検証報告

### 4. カナリーテスト追加
- `tools/smokes/v2/profiles/quick/core/phase2100/` 配下に複数追加
- emit_boxcall_length_canary_vm.sh
- stageb_parser_loop_json_canary_vm.sh
- 他

### 受け入れ基準
-  delegate パス: rc=10 返す
-  FORCE パス: rc=10 返す(既存)
-  MIR 構造: 正しい PHI incoming と compare
-  既定挙動: 不変(dev トグルのみ)
