%% The agents seam: one handler, registered by the session registry when the
%% daemon starts, that answers what an agent asks of other sessions. Calls come
%% from kernel host routes, outside every actor. The handler answers a Gleam
%% Result(Json, String); a missing or crashed handler is an error, not a crash.
