Parses the decklist and returns a Deck object. Public: Parse and return a Deck. Idempotent. 日本語: 解析して Deck を返します。多重実行に耐性があります。

How it works (EN): Streams the decklist line-by-line, skipping section headers and comments, toggling sideboard state as appropriate, and parsing counts/names using a permissive regex that tolerates set codes and collector numbers.

仕組み (JA): デッキリストを 1 行ずつ処理し、セクション見出しやコメントをスキップ、適宜サイドボード状態を切替えながら、枚数とカード名を寛容な正規表現で抽出します (セットコードやコレクタ番号を許容)。
