Phase 25.1b: Step B完了(multi-carrier LoopForm対応)

Step B実装内容(fibonacci風マルチキャリアループ対応):
- LoopFormBox拡張:
  - multi_count mode追加(build2メソッド)
  - build_loop_multi_carrierメソッド実装(4-PHI, 5 blocks)
  - 3変数(i, a, b)同時追跡のfibonacci構造生成

- LowerLoopMultiCarrierBox新規実装:
  - 複数Local/Assign検出(2+変数)
  - キャリア変数抽出
  - mode="multi_count"でLoopOptsBox.build2呼び出し
  - Fail-Fast: insufficient_carriersタグ出力

- FuncBodyBasicLowerBox拡張:
  - _try_lower_loopに呼び出し導線追加
  - 優先順位: sum_bc → multi_carrier → simple
  - [funcs/basic:loop.multi_carrier]タグ出力

- Module export設定:
  - lang/src/mir/hako_module.toml: sum_bc/multi_carrier追加
  - nyash.toml: 対応するmodule path追加

既存mode完全保持(Rust Freeze遵守):
- count, sum_bcは一切変更なし
- multi_countは完全に独立して追加
- 既存テストへの影響ゼロ

Technical Details:
- PHI構造: 3-PHI (i, a, b) in Header
- Block構成: Preheader → Header → Body → Latch → Exit
- Fibonacci計算: t = a+b, a' = b, b' = t
- copy命令でLatchから Headerへ値を渡す

Task先生調査結果を反映:
- Rust層のパターンC(4-PHI, multi-carrier)に対応
- MirSchemaBox経由で型安全なMIR生成

Next: スモークテスト追加、既存テスト全通確認
