FrameCaptureService class abstract interface

Captures the pixels of one already-pumped frame as a RawFrame.

The render loop owns the clock: it seeks the controller, pumps the tree, and only then asks this service for the pixels. Implementations therefore never advance time, never await anything frame-dependent, and capture the same pixels for an identical pumped tree, which is what the frame cache and the golden harness rely on.
