New ytsage/gui/ytsage_gui_player.py: - MpvRenderWidget hosts libmpv through MpvRenderContext in a QOpenGLWidget - works on native Wayland where wid-embedding cannot - with all mpv-thread callbacks marshalled to the GUI thread via queued signals only. - PlayerPanel adds transport controls: play/pause, seek slider, time display, quality selector (caps ytdl-format height and reloads in place), speed, volume (persisted), subtitle toggle, fullscreen (reparent to top-level window), and Space/F/Escape keys. - Playback resolves watch URLs through mpv's ytdl_hook pointed at the app-managed SHA256-verified yt-dlp binary (script-opts ytdl_hook-ytdl_path), inheriting cookies and proxy settings via ytdl-raw-options - stream freshness, DASH muxing and nsig handling stay in yt-dlp's hands. New ytsage/core/ytsage_mpv.py probes libmpv availability; without it the Watch UI shows a per-OS install hint and everything else works. python-mpv added to dependencies (libmpv itself is a system package). Config gains player.* and feed.* defaults. Verified on Wayland: real YouTube video streams with position/duration signals flowing and no thread-safety errors.

libmpv availability probe

=========================
|
|
|
|
python-mpv is a ctypes binding: importing it raises OSError when the libmpv
|
|
shared library is missing from the system. All player code must import mpv
|
|
through probe_player() so the rest of the app (search, browse, downloads)
|
|
keeps working without libmpv installed.
