feat: бинокулярный видеорендер в app-glasses + иммерсивный режим + тест-план

- render/: Grafika-связка (EglCore/WindowSurface/FullFrameRect/Texture2dProgram/GlUtil/Drawable2d/EglSurfaceBase) — перенос из pair-view
- ui/BinocularVideoPlayer: один SimpleExoPlayer → SurfaceTexture → EGL-блит в оба глаза (EglVideoRenderer шарится между LEFT/RIGHT)
- ui/ViewUtils: Binocular/BinocularScreenSide/BinocularScreenSize (Compose, из pair-view)
- ui/GlassesMovieScreen: «нос к носу», calculateVideoSizeFull, FLAG_KEEP_SCREEN_ON
- MovieController: PlayVideo/MediaCommand (PLAY/PAUSE/TOGGLE/SEEK/CLOSE), доступ к ExoPlayer только с main-потока
- HostConnection: PlayVideo→плеер, реальная позиция в PlaybackPosition (withContext Main)
- MainActivity: иммерсивный режим (setDecorFitsSystemWindows(false) + hide systemBars)
- TESTING.md: 10 тест-кейсов human-style; QA-прогон (opencode, 88.19) — 10/10 ПРОЙДЕН
