Any user can REPORT <nick|#channel> <reason>; filing is rate-limited per
reporter. Reports are an event-sourced, federated queue operators review
with LIST / VIEW / CLOSE / DEL. The interconnection: because a filed report
is an event, the engine's audit feed already announces it to the staff
channel and records it in the searchable action log — so OperServ
LOGSEARCH finds a report by any word in it, tying reports into the same
trail as bans, kicks, and everything else. Opt-in (add "reportserv").
