Cross-chat context awareness for quick chats

When I start a new chat session, there's no awareness of previous chats. If I discussed something 8 sessions ago, I have to manually search for that specific chat to bring in the context. This is especially painful for heavy quick chat users.

What I'd love: the agent should be able to reference or recall relevant context from prior chat sessions without me needing to find and re-open them. Not full history replay, just enough awareness that I'm not starting from zero every time.

Right now the workaround is keeping one mega-chat that never ends, which doesn't scale and defeats the purpose of quick chats. Another workaround is manually storing things in the built-in sqlite db, but that's fragile and could get wiped on an update.

This would make the app feel like it actually knows me over time, not just within a single session.

このリクエストは /chat パスに関するものですが、実装ファイル、テスト、具体的なエントリーポイントは特定されていません。まず quick-chat のセッションと履歴の処理箇所を見つけ、次に、以前のチャットを手動で再度開くことなく、新しいセッションで関連する過去のコンテキストをどのように選択して検証するかを定義してください。
