Adds a new videoInput node type that allows users to drag-and-drop or
browse for video files (MP4, WebM, QuickTime), preview them inline with
native video controls, and feed them into downstream video processing
nodes. Includes full media externalization/hydration support, Shift+Y
keyboard shortcut, and ConnectionDropMenu integration.
