feat: Phase 2.4 NyRT→NyKernel Architecture Revolution 100%完了！

Browse Source 
ChatGPT5 Pro設計分析による42%コード削減の完全実現：
- crates/nyrt → crates/nyash_kernel 完全移行
- with_legacy_vm_args系統11箇所削除（encode/birth/future/invoke系）
- Plugin-First Architecture統一（VM依存根絶）
- libnyash_kernel.a生成成功（0エラー・0警告）
- LLVM統合更新（build_llvm.sh, ny-llvmc対応）
