Image cards, thumbnails, the lightbox, and `clide image show` rendered via Image.file, whose FileImage keys Flutter's imageCache by (path, scale) only — so overwriting a file at the same path handed back the previously decoded frame (hit live re-exporting a wireframe PNG). Add ClideFileImage, a FileImage that folds mtime + size into ==/hashCode so an in-place change is a fresh cache key (miss → re-decode), and route the five Image.file sites through it.
