- build.ts: darwin compile now exits 1 when mpv is absent — CI can no
longer ship a PodTui.app without its bundled player (0.4.0 did, killing
Now Playing attribution).
- audio-player.ts: the bundled mpv is probed (--version) at first resolve;
it links against brew's dylibs, and a Homebrew ffmpeg major upgrade can
break it — fall back to PATH mpv so audio survives (icon degrades to
blank instead of playback dying). Probed once per process.
- release.yml: brew install mpv on darwin runners; smoke test now asserts
the tarball's PodTui.app has a launchable mpv signed with the
com.mikefreno.podtui identifier.
