useVideoPlayer

Bind a VideoMedia handle to a caller-owned <video> element.

Vue idioms:

• videoRef accepts a raw HTMLVideoElement, a Ref<...>, or a getter. Pair with <video ref="video" /> in the template, then pass the template ref straight in.
• The composable never injects DOM nor overrides layout.
• On scope disposal (or when media changes) the composable calls media.revoke() to free the object URL.
