- Linux: Tauri packs a window's webviews into one GTK box with equal
shares and ignores their bounds, so the title bar took half the window.
The title bar webview now has a fixed height and no share; the box's
border is the resize frame (none when maximized).
- tauri-plugin-updater: checks llembas.eu/desktop/latest.json at start
and every 6 h, an update button in the title bar and menu entries,
.deb via pkexec, AppImage in place, then restart. Packages signed with
the updater's minisign key; requireSignedVersion on.
scripts/publish-update.sh signs a GitHub release and writes the manifest.
