M7 DONE via delegation — pv.youtube plays HD with audio

After hitting the segment-timing wall on our hand-rolled DASH MPD
(audio drifted -25s -> -44s behind video on long content), pivoted to
delegating playback to plugin.video.youtube v7.4.3 which already has
years of sidx-parsed SegmentTimeline + multi-client fallback work.

torttube._play() now:
  1. Tries _delegate_to_pv_youtube(yt_id) — sets a resolved URL of
     'plugin://plugin.video.youtube/play/?video_id=<id>'. Kodi
     chain-resolves to pv.youtube which builds the proper MPD and
     hands inputstream.adaptive a correctly-aligned manifest. Default.
  2. Falls back to our DASH builder (still in code, gated by
     'dash_enabled' setting + dash.on marker) if pv.youtube is absent.
  3. Falls through to yt-dlp progressive 360p as the final safety net.

When delegating, we skip our SponsorBlock monitor — pv.youtube has its
own and would double-skip otherwise.

Verified live on a LibreELEC Pi: LTT 'Trump Phone' (which crashed
our DASH with audio sync errors growing to -44s) now plays HD with
audio synced. 'Please sign in' message in log is from the tv_unplugged
Innertube client; pv.youtube falls back to a working client
automatically — no user account required.

Settings: prefer_pv_youtube boolean (default true). Addon v0.0.11.
