LightcraftApp::run_typed keeps the engine's ErrorKind in a CommandError;
run() is run_typed(..).map_err(|e| e.message), so its callers are
untouched. The face detector offer and the SAM 3 download dialog decide
on ModelMissing, the SAM 3 download toast and the Apple Photos note on
the `cancelled` flag, and a Lightroom inspect/import on its own cancel
flag only, so a failure that mentions "cancelled" is still a failure.
