- Show full session ID in a fixed-width column for easy scanning
- Pad row numbers to 2 digits to keep alignment past 9 entries
- Always show session source (tui/cli) instead of conditionally hiding it
- Use Box-based column layout so ID, metadata, and title don't run together
- session.list RPC now queries both tui and cli sources, merged by recency
- Session picker shows source label for non-tui sessions (e.g. ", cli")
- Added source field to SessionItem interface
