docs: Update JoinIR design map + organize CLAUDE.md (Phase 135 follow-up)
## Changes
### joinir-design-map.md
- Added "Allocator SSOT (Phase 135)" section
- Principle: All ValueId allocation via single allocator (ConditionContext.alloc_value)
- Prohibited: Internal counters in ConditionLoweringBox/ExprLowerer
- Reason: Collisions with JoinIR params (ValueId(1000+)) overwrite header PHI dst
- Detection: --verify catches "Value %N defined multiple times"
- Added "Boundary Injection SSA (Phase 135)" section
- Principle: condition_bindings allow aliases, but injected Copy dst must be unique
- Fail-Fast: Error on different sources to same dst
- Reason: Breaks MIR SSA, causes undefined behavior in VM/LLVM
- Added "Box Implementation Checklist"
- 4-point checklist for Box implementation/changes
- Covers: --verify, smoke tests, allocator usage, boundary injection
### CLAUDE.md
- Organized "重要設計書" section with clearer structure
- Added "JoinIR 設計図" subsection with both documents:
- JoinIR アーキテクチャ概要 (normative SSOT for contracts/invariants)
- JoinIR 設計マップ (navigation SSOT for implementation)
- Grouped related documents: JoinIR, MIR・言語仕様
## Context
Phase 135 revealed that missing "what not to do" (invariants/contracts) in
design docs led to Allocator SSOT violations and ValueId collisions.
This update ensures future Box implementations can follow clear contracts.

feat(mir): Phase 131-11-E - TypeFacts/TypeDemands 分離（SSOT）
## 実装内容
### 1) Rust MIR Builder (ops.rs + lifecycle.rs)
- OperandTypeClass で型分類（String/Integer/Unknown）
- BinOp 型推論: Integer + Unknown → Integer
- lifecycle.rs に repropagate_binop_types() パス追加
- PHI 型解決後に BinOp 型を再計算
### 2) JSON Emission (mir_json_emit.rs)
- 結果ベースの dst_type 発行に変更
- Integer → "i64", String → {kind: handle, box_type: StringBox}
### 3) Python LLVM Backend (binop.py)
- dst_type を確実な情報として使用
- dst_type != None なら優先して処理
## 結果
- ✅ MIR: PHI/BinOp が Integer として正しく型付け
- ✅ VM: `Result: 3` （正しい出力）
- ✅ JSON: `dst_type: "i64"` を発行
- ❓ LLVM: 別の codegen 問題の可能性あり
## SSOT 設計達成
- TypeFacts（事実）: 定義命令から推論
- TypeDemands（要求）: 使用箇所の coercion で吸収
- 後方伝播なし: Fail-Fast に統一
