Redesign session selector with multi-line layout

- Custom SessionList component with 2 lines per item
- First line: message text (bold when selected)
- Second line: metadata (time · message count) in dim
- Blue › cursor for selected item
- Added "Resume Session" header
- Handle Ctrl+C (‹x03›) in SelectList for consistency
- Improved date formatting (38 minutes ago, 8 hours ago, etc.)
