Subject: [PATCH] Add recent sessions display on home page
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Users can now see and click on previous sessions from the home page without
having to create a new session. Shows up to 6 most recent sessions with:
- Session ID and status (created/completed)
- First 100 chars of prompt
- Session creation date

Features:
- Fetches sessions from new GET /api/collaborate endpoint
- Clickable cards to open existing sessions
- Beautiful glassmorphic cards with hover effects
- Responsive grid layout
