GNOME resolves the MPRIS media-widget app icon via DesktopEntry -> the installed
<id>.desktop -> Icon=. Rename the Arch desktop file to com.blitzfc.qbz.desktop,
set Icon=com.blitzfc.qbz, and install the hicolor icon as com.blitzfc.qbz.png so
the basename matches the published DesktopEntry. Other channels (AUR/Gentoo/Snap
+ Tauri bundle/release workflow) documented in qbz-nix-docs (release-time,
build-test required). Flatpak was already correct.

New frontend-agnostic crate qbz-media-controls (ADR-006): one MediaIntegration
trait, cfg-split backends. Linux uses mpris-server and publishes the MPRIS
org.mpris.MediaPlayer2.DesktopEntry property as com.blitzfc.qbz — the only way
GNOME Shell resolves the app icon for its media widget (souvlaki, the old
cross-platform crate, never set it, so GNOME showed no icon; KDE is lenient).
macOS/Windows keep souvlaki (MediaRemote/SMTC), where the icon comes from the
app bundle, not a DesktopEntry. The Linux server runs on a dedicated thread
with its own tokio runtime; state arrives over an async channel.
Wired into qbz-slint via src/media_controls.rs: started on shell entry,
metadata/playback pushed from the playback paths (mirroring the tray), and
inbound control events (media keys, the desktop media widget, Now Playing)
dispatched to the player through the existing QConnect-aware helpers. Both
Linux and macOS compile clean.
