tomoaki c117a04035 fix(rewrite): toString normalization to BoxCall(slot #0) - Phase 287 P4
Root cause: toString/stringify/str were being rewritten to Global/Method calls
with class inference, causing Main.toString/0 to be called for primitives.

Fix (Box-First + Legacy Deletion):
1.  MIR Builder - toString normalization (special.rs)
   - ALWAYS emit BoxCall with method_id=0 for toString/stringify/str
   - Do NOT rewrite to Global(Class.str/0) or Method calls
   - DELETED 70+ lines of complex class inference logic
   - Primitive guard with method name filter (known.rs)

2.  JSON Serializer - method_id output (mir_json_emit.rs)
   - Include method_id field in BoxCall JSON for LLVM

3.  LLVM Backend - universal slot #0 support
   - Extract method_id from JSON (instruction_lower.py)
   - Box primitives via nyash.box.from_i64 (boxcall.py)
   - Invoke toString via plugin system with method_id=0
   - ⚠️ TODO: Add nyash.integer.tostring_h to kernel

Test Results:
 VM: local x = 1; print(x.toString()) → "1" (PASS)
 VM: array_length test (boxed Integer) → PASS
⚠️ LLVM: Compiles successfully, needs kernel function

SSOT: slot_registry - toString is ALWAYS universal slot #0

Legacy Deleted:
- special.rs: Complex class inference rewrite (~70 lines)
- special.rs: Unique suffix fallback for toString
- special.rs: Main box special handling

Files changed:
- src/mir/builder/rewrite/special.rs (try_early_str_like_to_dst)
- src/mir/builder/rewrite/known.rs (primitive guards x4)
- src/runner/mir_json_emit.rs (method_id serialization x2)
- src/llvm_py/builders/instruction_lower.py (method_id extraction)
- src/llvm_py/instructions/boxcall.py (slot #0 handler)
- docs/reference/language/quick-reference.md (toString SSOT)

  3. 設計背景を知りたい../design/
  4. 調査ログを見たい../investigations/

Phase 命名規則

  • ファイル名: phase-<N>-<title>/ (例: phase-131/)
  • 文書名: <N>-<NN>-<topic>.md (例: 131-11-case-c-summary.md)
    • Phase 番号で自然にソート可能
    • 同一 Phase 内で段階的に追跡可能

作成ルールSSOT

詳しくは ../DOCS_LAYOUT.md を参照。

  • 置き場所: phases/phase-<N>/ 配下のみ
  • 内容: Phase の実装記録・進捗・チェックリスト・検証結果
  • 避けるべき: 複数 Phase で参照される設計・アーキテクチャ(→ design/ へ)
