The video-reference-analyst capability audit pre-locked Remotion as the
default composition engine ('Remotion is the default ... Never default to
FFmpeg when Remotion is available'). Because the analyst skill runs first
in any reference-led flow, this silently locked the runtime before the user
was ever offered a choice — violating the 'Present Both Composition Runtimes
(HARD RULE)' in AGENT_GUIDE.md, which forbids silently picking a default and
treats Remotion and HyperFrames as parallel, non-ranked runtimes.
It also omitted HyperFrames from the engine list entirely, so it was never
surfaced as an option in the reference-led path.
Update Step 2 (Capability Audit) to:
- add HyperFrames to the audited runtime list
- remove the 'Remotion is the default / preferred' framing
- defer engine selection to the AGENT_GUIDE 'Present Both' gate
- keep FFmpeg scoped to standalone ops, not composition
