Build error: `cannot inherit from non-open class 'VideoView' outside of its
defining module` — VideoView is public, not open, so it can't be subclassed
in the plugin module. Reworked TileVideoView from a VideoView subclass into a
UIView CONTAINER that holds a VideoView: the container is frame-synced to the
web tile rect, the pinch/pan zoom transform lives on the inner video (so it
never fights the position poll), and the name/mute overlays sit on the
container so they no longer scale with zoom. track/layoutMode are forwarded.
Also silenced the extension warning: SampleHandler now restates
`@unchecked Sendable`.
The broadcast extension itself compiled + linked in the failed build, so the
SPM-linked extension injection + App Group setup are working.
