usePipSession() owns an off-screen div under document.body; adopt(video) moves the element there so it survives the unmount of whatever view rendered it (a Teleport and a KeepAlive'd view both move their subtree on deactivation, which the picture-in-picture spec treats as removal). release() tears down playback and detaches the element; a leavepictureinpicture listener on the adopted element is the primary release path so an orphaned owner can never leak it. Also adds isPipSupported() to pip.ts — a call-time version of the existing import-time pipSupported const, needed because a test can't restub document.pictureInPictureEnabled after import. togglePip and pipSupported are unchanged.
