Phase 12: TypeBox革命とJIT制御フロー修正 - セルフホスティングへの道

Browse Source 
## 🔥 TypeBox ABI革命（セルフホスティング実現）
- Nyash ABIをC実装TypeBoxで提供する画期的設計
- Gemini/Codexの深い考察を反映した詳細仕様書作成
- 16バイトアライメント、セレクターキャッシング、弱参照等の具体実装案
- Rust依存を完全排除し、セルフホスティングへの明確な道筋を確立

## 🎯 JIT制御フロー根本修正（ChatGPT5の25分長考の成果）
- ブロック挿入点の明確化: switch_to_block()で各ブロックemit開始時に切替
- シール戦略の簡潔化: br/jump直後のseal撤廃、最終シールに一本化
- PHI最小経路実装: ブロック引数の事前プリスキャン、後付けPHI問題解決
- Cranelift制約対応: 開始済みブロックへのappend禁止を正しく実装

## 📚 ドキュメント更新
- Phase 12全体のセルフホスティング対応更新
- NYASH-ABI-C-IMPLEMENTATION.md: 実装仕様書作成
- gemini-codex-deep-thoughts.md: AI専門家の考察アーカイブ
- 各種README/TASKS更新でセルフホスティング要件追加

## ✅ テスト結果
- mir-branch-ret: OK (Result: 1)
- mir-phi-min: OK (Result: 10)
- mir-branch-multi: OK (Result: 1)

「Everything is Box」の究極形態：ABIすらBoxとして扱う革命的設計！
