Subject: CGitのソーシャルアイコンをカスタム fork/branch SVG に変更
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

SocialIcons コンポーネントを上書きして、CGit 用に
git リポジトリを表す fork/branch アイコンを表示。

- src/components/starlight/SocialIcons.astro を新規作成
- Starlight の social icon はカスタム SVG を受け付けないため、
  コンポーネント上書きで対応
- X アイコンも併せてインライン化
