## What changed
- Show draft attachment thumbnails in reference order in inline and fullscreen views on supported terminals with local workspaces. Display a `+N` count for attachments that do not fit, and preserve editable image references when previews are unavailable or space is limited.
- Refresh previews when attached files change, apply image orientation metadata, and clear frame graphics before terminal handoffs, screen switches, and shutdown.
- Finish CLI subcommand dispatch before polling interactive TUI events.
## Testing
Add a regression test and snapshot covering thumbnail order, overflow, resizing, attachment deletion, file replacement, and fallback behavior in both inline and fullscreen views.
