"""``profiles.list`` re-parses a profile's ``profile.yaml`` for ui_meta only when it has changed.

The roster polls this every 5s per connection, and the listing already parsed that same file once
(``read_profile_meta``, for description/display_name) before parsing it again here for ui_meta.

The memo must be invisible: an edit — including one made through the ui_meta CAS writer, which
reads the raw document uncached and writes it back — has to show on the very next listing. And
``has_avatar`` is deliberately NOT cached, so an avatar dropped in without touching profile.yaml
still appears.
