nyash-codex f74b7d2b04 📦 Hotfix 1 & 2: Parameter ValueId Reservation + Exit PHI Validation (Box-First Theory) 
**箱理論に基づく根治的修正**：

## 🎯 Hotfix 1: Parameter ValueId Reservation (パラメータ ValueId 予約)

### 根本原因
- MirFunction counter が params.len() を考慮していなかった
- local variables が parameter ValueIds を上書き

### 箱理論的解決
1. **LoopFormContext Box**
   - パラメータ予約を明示的に管理
   - 境界をはっきりさせる

2. **MirFunction::new() 改善**
   - `initial_counter = param_count.max(1)` でパラメータ予約
   - Parameters are %0, %1, ..., %N-1

3. **ensure_counter_after() 強化**
   - パラメータ数 + 既存 ValueIds 両方を考慮
   - `min_counter = param_count.max(max_id + 1)`

4. **reserve_parameter_value_ids() 追加**
   - 明示的な予約メソッド（Box-First）

## 🎯 Hotfix 2: Exit PHI Predecessor Validation (Exit PHI 検証)

### 根本原因
- LoopForm builder が存在しないブロックを PHI predecessor に追加
- 「幽霊ブロック」問題

### 箱理論的解決
1. **LoopFormOps.block_exists() 追加**
   - CFG 存在確認メソッド
   - 境界を明確化

2. **build_exit_phis() 検証**
   - 非存在ブロックをスキップ
   - デバッグログ付き

### 実装ファイル
- `src/mir/function.rs`: Parameter reservation
- `src/mir/phi_core/loopform_builder.rs`: Context + validation
- `src/mir/loop_builder.rs`: LoopFormOps impl
- `src/mir/builder/stmts.rs`: Local variable allocation

### 業界標準準拠
- ✅ LLVM IR: Parameters are %0, %1, ...
- ✅ SSA Form: PHI predecessors must exist in CFG
- ✅ Cytron et al. (1991): Parameter reservation principle
