The playback data resolve — the one network request that must land
before open() — was kicked off only after the SharedPreferences load,
the Windows display-mode sync, the music-session teardown in
claimVideo(), Player construction, and (Android/Exo) a native
setLogLevel, so none of that setup overlapped the round trip.
Move the kickoff to immediately after the settings reads; the resolve
depends only on settings and provider lookups, so display sync, player
construction, and the whole mpv property chain now hide behind the
network latency instead of preceding it.
Also remove redundant work elsewhere on the start path: memoize
PlayerAndroid.getHeapSize (asked again on every open for an immutable
device value), skip the ten subtitle-style settings reads on mpv
backends where setSubtitleStyle is a no-op, and stop navigateToVideoPlayer
awaiting SettingsService.getInstance twice per launch — the external-player
read now sits behind the supportsExternalPlayers guard.
