### Fixed
- **Niri screen sharing works with the GNOME portal again.** Ryoku's
`GDK_BACKEND=wayland,x11,*` preference was inherited by
`xdg-desktop-portal-gnome`, which then treated the Niri session as an
incompatible display server and exposed Settings only, leaving OBS,
browsers and Electron clients without a ScreenCast backend. The portal
service now drops only `GDK_BACKEND`, while normal GTK applications keep
Ryoku's Wayland-first preference
(`shell/systemd/user/xdg-desktop-portal-gnome.service.d/10-ryoku.conf`).
- **The gap stream clears when it stops instead of freezing a frame.** A silent
bar with no drift left the last shader frame stuck in the gaps; it now hides,
so the stream reads as off, then on when audio returns

# Ryoku prefers Wayland for GTK applications through GDK_BACKEND, but
# xdg-desktop-portal-gnome uses the presence of that override when deciding
# whether it is running on a compatible GNOME/Niri session. When inherited
# under Niri it exposes Settings only and drops the ScreenCast interface.

# Keep the application-wide preference while removing it only from this
# portal backend.
