Add mobile camera capture, polaroid preview, gallery save & native share

- カメラ撮影 → プレビュー(ポラロイド風白縁)→ 保存 / ネイティブ共有 - iOS / Android のネイティブ実装(共有・ギャラリー保存・FileProvider) - iOS は共有シートのプリウォームで初回表示を軽減 - iOS Info.plist 用途説明をビルド後処理で自動付与 - Android パッケージ名ガードを有効化(ビルド前チェック) - README を整備、.gitignore に slnx / .vscode / .utmp を追加 Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
