init

Scaffold the host-repo conventions the hane skills expect — doc directories, document templates, a process.md skeleton, and optionally status labels and a rules directory. Trigger when the user says: "hane init", "init", "初期設定", "セットアップ", "scaffold", "hane を導入", "ディレクトリ構造をセットアップ", "set up hane", or similar phrases requesting host-repo setup for the hane skills.
