High severity:
- compose action エラー戻り値の validation キー統一（server.py）
- ppmck/pyxel タイ &amp; の duration 延長修正（_tie_pending フラグ導入）
- pyxel ネストリピート対応（RepeatFrame + イベントスナップショット方式）

Medium severity:
- 専用エラーコード追加: VALIDATION_MISSING_PARAMETER, VALIDATION_INVALID_MODE, VALIDATION_INVALID_ACTION
- SYSTEM_INTERNAL_ERROR キャッチ範囲拡大（compose/validate全体をtry/except）

Low severity:
- 設計書 line/column を1始まりに明記、APIレベルエラーコード追記

テスト: 129 passed, ruff: All checks passed
