mod/decide-batch triages a queue; mod/action-histogram summarizes outcomes by
action; mod/rule-coverage + mod/never-fired measure which rules fire across a
corpus — the empirical complement to lint's static unreachable check (lint finds
rules that can't fire; never-fired finds rules that didn't). +17 tests.
