#270 asked whether a model can be downloaded by hand and imported. It
already can - resolve_model_installation adopts a file at the managed
path once its SHA-256 matches the catalog pin - but nothing in the app
told the user where that path is. About reported the variant and its
state, not the location, so the answer was "go read the app data
layout".

Add the expected path to DebugInfo and to the About panel, and document
the three-step procedure in both READMEs. A digest that does not match
the pin is ignored and the normal download runs, so a wrong or partial
file cannot corrupt the install - worth saying out loud, because that is
what makes the manual route safe to recommend.
