release 1.3.2: update from Gitea, Linux-only CLI, desktop app for Linux and Windows

The updater reads latest.json from Gitea, built by scripts/make-latest-json.py
against the Gitea API (no gh CLI). Release workflow builds the Linux CLI and
the Linux+Windows desktop app, signs the updater artifacts and attaches
everything to the release.

Needs the repo secrets TAURI_SIGNING_PRIVATE_KEY and
TAURI_SIGNING_PRIVATE_KEY_PASSWORD, which I could not set (secret-store writes
are reserved for the user) - set them from ~/.tauri/guara-updater.key and
.pass before pushing a tag.
