### wai-quantum-desktop 0.1.1: an app on an external drive updates itself, and one on a disk image does not

The macOS app took any path under `/Volumes` to be its disk image, and any other path not to be. An app kept on an
external drive was told to move and did not update, while a disk image mounted elsewhere, or a copy Gatekeeper had
translocated, said it would update itself and could not. It now asks whether the volume it runs from can be written.

- **wai-quantum-desktop 0.1.1:** `update-status` and the updater read the volume's read-only flag, and say why when a
  copy cannot update. The disk image is the same as before. It also carries `tauri-plugin-updater` 2.14.1 and `zip` 9,
  past RUSTSEC-2026-0429. It is the first version with installers for every platform: the 0.1.0 release has none for
  macOS on Apple silicon, because this check stopped that build.
