nyash-codex 66fecd3d14 feat(joinir): Phase 34-2/34-3 JoinIR Frontend implementation ...

AST→JoinIR フロントエンド経路の基盤完成。simple/local pattern で
「値としての if」が同じ JoinIR Select に正規化されることを実証。

**Phase 34-2: Simple pattern 実装**
- AstToJoinIrLowerer::lower_program_json() 実装
- Program(JSON v0) → JoinModule 変換パイプライン確立
- IfSelectTest.test: if cond { return 10 } else { return 20 }
- 変数ID衝突バグ修正（params分スキップ）

**Phase 34-3: Local pattern 対応**
- lower_simple_if/lower_local_if 関数分岐実装
- IfSelectTest.local: 意味論的 local pattern 対応
- simple と local で JoinIR 出力が同じことを実証

**技術的成果**
- JoinIR = 意味論の SSOT: 構文の違いを Select に統一
- PHI 不要の証明: 値としての if は Select のみで表現可能
- テスト: 2 passed (simple + local)

**実装ファイル**
- src/mir/join_ir/frontend/ast_lowerer.rs (340 lines)
- src/mir/join_ir/frontend/mod.rs (46 lines)
- src/tests/joinir_frontend_if_select.rs (140 lines)
