Quality-gate Lows (BS03 r1): resolved_count always equalled
len(self._username_resolved_ids) (each name is discarded from to_resolve on
its first match, so it adds exactly one ID), and resolved_allowlist_user_ids
filtered isdigit()/"*" out of a set that only ever holds str(member.id) and is
always initialised in __init__ and reset by the resolver. Drop the counter, the
filter, the getattr fallback (no test builds the adapter without the resolver
and then calls the accessor) and the stale "Numeric only" docstring line.
Behaviour unchanged (probe-BS03-1 output identical before and after).
