Channels & cleanup

• !purge [n] (alias !clear) — delete the last n messages.
• !lockdown [#channel] [duration] — lock a channel; !unlock [#channel] to reopen.
• !inspect [@user] — account age, join date, roles, timeout status.

AntiRaid, AutoMod and the Chat Filter run automatically — see their config on the dashboard (!antiraid, !automod, !chatfilter show the current state).
