Subject: [PATCH] fix: respect capture_on_queue flag in
 WebcamCapture.IS_CHANGED

When capture_on_queue is True, the node should always re-execute on
each queue operation. Previously IS_CHANGED ignored this flag and always
returned the file hash, causing the node to be skipped if the cached
image hadn't changed on disk - defeating the purpose of the option.
