Add moderation system with deterministic detection and strike ladder

Browse Source

Deterministic-only detection (no LLM): word list with precompiled
leetspeak variation matching, text/image flood, wall of text, repeated
messages (Levenshtein similarity), mention flooding, link rate limiting
for new members, invite flooding, join/leave cycling detection.

Three-strike response ladder: warn + redact → temp mute → permanent ban.
Strikes expire after configurable period. Admin room notifications with
context cards. DMs over public callouts.

Admin commands: !mod warn/mute/unmute/ban/strikes/forgive/history/reload/
status/test. All require ADMIN_USERS membership.

Feature-flagged: disabled by default, set FEATURE_MODERATION=true to
enable. All thresholds configurable via env vars. New member grace
period with stricter thresholds. Word list hot-reload via !mod reload.
