Subject: feat(ppmck): mckc準拠の構文拡張とIR保持コマンド追加
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- @をデューティ比、qをクオンタイズに修正（mckc原本準拠）
- ^タイ、Dディチューン、sスイープ、v+/v-相対音量を追加
- @v/@@/@MP/@EP/@EN エンベロープ・LFO系を構文解析してIR保持
- 上記IR保持コマンドは合成未対応を SEMANTIC_UNSUPPORTED_FEATURE で警告
- Design.md / MML_BNF.md を更新
- 全200テスト + ruff チェック通過
