What's Changed
- Coordinate Launcher updates with the installed A0 CLI by stopping active Host access gateways and running the CLI update handoff before installing the downloaded Launcher release.
- Keep A0 CLI update failures non-blocking while retaining diagnostic logs for recovery.
- Add pointer-driven reordering for attached Instance tabs with a floating preview and clear insertion marker.
- Detach an Instance by dropping its tab outside the strip through the existing shell-owned reparenting flow.
- Validate attached tab order in the shell, preserve detached tab slots, and expand focused coverage for updater handoff and tab ordering.
Release workflows build from the v1.5 tag and upload the executable matrix, updater metadata, and content.json.
