[Feature]: watch if ffmpeg is available on the system

[g3nsvrv]

What problem does this solve?

if ffmpeg is installed, stemdeck does not uses it, actually it downloads his own version, compiled for macOS 15, and I'm using macOS 13... (so it does not work)... By changing the ffmpeg binary is enough to resolve this issue, and the app works just fine.

Proposed solution

you could use a:

if [ -z "$(which ffmpeg)" ]
then
	download ffmpeg from your page
fi
else
	use what is on the system
fi

Opened #420 to address this.

The desktop app's macOS setup always downloaded its own pinned FFmpeg build, even when a working system install was already on PATH. It now checks PATH first (matching what the Linux build already did) and only downloads when no compatible system FFmpeg is found. "Compatible" now means the binary actually launches on your macOS version and has every encoder StemDeck needs (previously only a launch check was done).

Docker is unrelated to this, it already installs FFmpeg via apt in the image.

Will link this issue as closed once #420 merges.
