- docs/architecture/models-cache-invalidation.md: add 'Invalidation modes'
section describing delete_disk=True/False and why /api/profile/switch
uses the memory-only mode (fingerprint-guarded per-profile disk cache).
- tests: replace the source-text scan of the switch route with two executed
routes.handle_post tests: one captures invalidate_models_cache kwargs and
asserts exactly [((), {'delete_disk': False})]; one runs the real
invalidate_models_cache and asserts the disk file survives while the
in-memory catalog is dropped. Both fail if the route reverts to the
default delete_disk=True.
