Add background podcast generation and UX improvements
Features: - Background podcast generation (navigate away while processing!) - Podcast status tracking (pending/in_progress/completed/failed) - Database-backed task queue (no external dependencies) - Podcast length control with slider (5-30 minutes) - Fixed podcast delete to update UI immediately - Collapsible source citations in chat (dropdown with count) - Real-time status checking for background tasks Technical: - Created background_tasks.py module - Added background_tasks table to database - Threading-based background execution - Task status tracking: PENDING, IN_PROGRESS, COMPLETED, FAILED - Proper database session management in shared notebooks - Fixed SQLAlchemy DetachedInstanceError in sharing view UX Improvements: - "Generate in Background" button instead of blocking - Status indicator shows when podcast is generating - "Check Status" refresh button - Sources collapsed by default with count badge - Podcast delete shows success message before rerun - Can navigate away during long-running operations 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
