visual_capture.gd runs via `godot -s`, where the `class_name` registry isn't
populated — so the bare `Protocol.decode_snapshot()` reference failed to
compile, breaking ALL --screenshot/--movie/golden captures (not just the
replay scenarios that use it). Instantiate the script and call the static
decoder on the instance (then free), matching the file's existing -s-mode
load() workaround for VisualScenarios.
