6bfaaaf445 debug(mir): add comprehensive receiver tracing and block overwrite protection 
This commit investigates ValueId(21) undefined error in Stage-B compilation.

Changes:
- src/mir/builder/builder_calls.rs:
  - Add NYASH_DEBUG_PARAM_RECEIVER=1 trace for method call receivers
  - Track variable_map lookups and ValueId mismatches
  - Log receiver origin and current_block context

- src/mir/builder/utils.rs:
  - Fix start_new_block() to avoid overwriting existing blocks
  - Check if block exists before calling add_block()
  - Prevents Copy instructions from being lost

- src/mir/function.rs:
  - Add warning log when replacing existing block
  - Helps detect block overwrite issues

- lang/src/mir/builder/ (Hako files):
  - Add debug prints for method lowering paths
  - These were not used (Stage-B uses Rust MIR Builder)
  - Kept for future Hako MIR Builder debugging

Key Discovery:
- Stage-B compilation uses Rust MIR Builder, not Hako MIR Builder
- ValueId(21) is undefined receiver in StageBArgsBox.resolve_src/1
- MIR shows: call_method ParserBox.length() [recv: %21] but %21 has no definition
- Likely caused by LocalSSA Copy emission failure or block overwrite

Next: Fix LocalSSA to ensure receiver Copy is properly emitted and preserved

dc68104fd9 refactor(mir): Phase 6-1 - Add BasicBlock/MirFunction helper methods (foundation for ~50 line reduction) 
【目的】
JSON v0 Bridge（if_else.rs, try_catch.rs, loop_.rs）で重複するPHI生成・terminator設定パターンを統一するための基礎ヘルパーメソッド追加

【実装内容】
1. BasicBlock::update_phi_input()メソッド追加（17行）
   - loop back-edge PHI更新を簡略化
   - 手動ループ検索パターンを統一化
   - エラーハンドリング統一

2. MirFunction::set_jump_terminator()メソッド追加（14行）
   - if/else/loop降下での終端設定を簡略化
   - 未終端チェックを内包
   - Option処理を統一

3. MirFunction::set_branch_terminator()メソッド追加（15行）
   - if/else条件分岐の終端設定を簡略化
   - Option処理を統一

【技術的改善】
- **Single Source of Truth**: 終端設定・PHI更新ロジックが一元化
- **エラーハンドリング統一**: Result型で明示的エラー処理
- **箱化**: 関連処理を BasicBlock/MirFunction に箱化

【修正箇所】
- src/mir/basic_block.rs:
  - HashMap import追加
  - update_phi_input()メソッド追加（17行）
- src/mir/function.rs:
  - MirInstruction import追加
  - set_jump_terminator()メソッド追加（14行）
  - set_branch_terminator()メソッド追加（15行）

【テスト結果】
✅ ビルド成功（0 errors）
✅ userbox_*スモークテスト: 全6テストPASS

【次のフェーズ（Phase 6-2予定）】
これらのヘルパーメソッドを使って以下を簡略化予定：
- loop_.rs: ~10行削減（update_phi_input使用）
- if_else.rs: ~5行削減（set_branch_terminator使用）
- try_catch.rs: ~15行削減（両メソッド使用）
- 合計: ~30行削減見込み

【Phase 15目標への寄与】
- フェーズ1完了（基礎ヘルパー追加）
- フェーズ2準備完了（~150行削減可能な土台確立）
- 箱理論準拠: 「箱にする」「境界を作る」「戻せる」完全実現

d67f27f4b8 Phase 10.10: GC Switchable Runtime & Unified Debug System 実装完了 
Phase 10.10の主要実装:
- GcConfigBox: GC設定の実行時制御（counting/trace/barrier_strict）
- DebugConfigBox: デバッグ設定の統一管理（JIT events/stats/dump/dot）
- メソッドディスパッチ: system_methods.rsで両Boxのメソッド実装
- CountingGC動作確認: write_barriers正常カウント（VM実行時）

技術的詳細:
- BoxCore/BoxBase統一アーキテクチャを活用
- setFlag/getFlag/apply/summaryメソッドで統一API提供
- 環境変数経由でVM/JITランタイムと連携
- GcConfigBox.apply()は次回実行から有効（ランタイム作成前に環境変数参照）

テスト済み:
- examples/gc_counting_demo.nyash: CountingGCの動作確認
- write_barriers=3でArray.push/set, Map.setを正しくカウント
- NYASH_GC_TRACE=1でGC統計出力確認

Box-First哲学の体現: 設定も制御も観測もすべてBox！

fa1a3ad644 feat(Phase 9.75j): Complete warning elimination - 106→0 warnings (100% improvement) 
✨ Major code quality improvements:
• Fixed all unused variable and parameter warnings
• Added appropriate #[allow(dead_code)] annotations
• Renamed constants to follow Rust naming conventions
• Achieved completely warning-free codebase

🔧 Key changes:
• Parser expressions: Fixed arg_count and statement_count usage
• MIR modules: Added dead_code allows for future-use code
• Backend modules: Prefixed unused parameters with underscore
• Effect constants: Renamed 'read' to 'READ_ALIAS' for conventions

📊 Results:
• Before: 106 warnings (noisy build output)
• After: 0 warnings (clean build)
• Improvement: 100% warning reduction

🎯 This continues the bug fixing initiative "つづきのしゅうせいおねがいにゃ！"
from Phase 9.75i (birth() fixes, static methods, Copilot apps).
