- Unify sidecar key name to camelCase cursorRecordingData (was mixing
cursor-recording-data and cursorRecordingData in the same checklist)
- Graceful-degradation test now removes both binary copies so the
missing-helper fallback is actually exercised (build/ and bin/darwin-*)
- Healthy recording section points to <videoPath>.cursor.json sidecar
instead of the .openscreen project file, which does not embed cursor data
Documents the cursor helper binary, permissions, manual test checklist,
expected sidecar shape, and known limitations for the darwin native
cursor path.
