What happened?

Play/pause commands coming from the main process — media keys, the tray menu's Play/Pause entry, MPRIS — do nothing while an internet radio station is loaded. It fails even with the window focused, and even when the station is only loaded and paused.

Cause — in the renderer's main-process listener hook, every media command is short-circuited as soon as a station is loaded, and nothing forwards it to the radio player:

const isRadioLoaded = useIsRadioLoaded();   // !!currentStreamUrl

mpvPlayerListener.rendererPlayPause(() => { isRadioLoaded || mediaTogglePlayPause() });
mpvPlayerListener.rendererPlay(() => { isRadioLoaded || mediaPlay() });
mpvPlayerListener.rendererPause(() => { isRadioLoaded || mediaPause() });

(Identifiers recovered from the 1.15.1 bundle: Ds.rendererPlayPause(()=>{e||h()}), where e comes from the selector t => !!t.currentStreamUrl on the radio store.)

The guard correctly keeps the queue player from fighting the radio player — I assume it came from #1490 — but the command is then simply lost, because the radio player is a separate player with its own store actions. The result is that a radio station can only be paused from inside the window, with the mouse.

The UI button handles both cases properly:

const { currentStreamUrl } = useRadioStore();
const isPlaying = useRadioIsPlaying();
const { pause, play } = useRadioActions();

const onClick = () => { isPlaying ? pause() : currentStreamUrl && play() };

Suggested fix — route the listeners to the radio actions when a station is loaded, reusing that same logic:

mpvPlayerListener.rendererPlayPause(() => {
    if (isRadioLoaded) {
        const radio = useRadioStore.getState();
        radio.isPlaying ? radio.actions.pause() : radio.actions.play();
    } else {
        mediaTogglePlayPause();
    }
});

with the matching one-sided variants for rendererPlay and rendererPause.

I applied this to my local build (1.15.1, Ubuntu 26.04, GNOME/Wayland, mpv backend) together with the companion MPRIS fix, and the media keys now pause and resume a radio stream correctly.

rendererNext / rendererPrevious are gated the same way. I left them alone since skipping has no obvious meaning on a continuous stream, but they might be worth routing to "previous/next station" or left as explicit no-ops.

Steps to reproduce

1. On a Linux desktop, play any internet radio station.
2. Focus the Feishin window, then press the play/pause media key. Nothing happens.
3. Same with the Play/Pause entry of the tray menu.
4. The play/pause button inside the window works — only commands coming from the main process are lost.

Companion issue: #2304 — on Linux the command doesn't even reach the renderer until that MPRIS guard is fixed.
