The GameStream video path (open_gs_virtual_source) ran the Linux compositor-
detection state machine on every platform. On Windows detect_active_session()
returns None and vdisplay::detect() bails ("could not detect compositor ...
XDG_CURRENT_DESKTOP=''"), killing the video thread right after RTSP PLAY — so a
Moonlight client paired, negotiated, then black-screened and dropped.
The native punktfunk/1 path already guards this (resolve_compositor returns a
placeholder Compositor on Windows, since vdisplay::open ignores the compositor
arg there and always uses the pf-vdisplay IddCx backend). Mirror that guard in
the GameStream path: short-circuit to a placeholder on Windows, keep the Linux
session detection (apply_session_env/apply_input_env) under cfg(not(windows)).
Validated live: Moonlight -> this box now creates the pf-vdisplay virtual
monitor, attaches the IDD-push ring, and NVENC streams 5120x1440@240.
