feat(bot): enhanced moderation — beats Rose/GroupHelp/Shieldy/Combot

CRYPTO-SPECIFIC:
- Auto scam address detection (queries RAG 20 collections in real-time)
- Phishing link filter (claim/airdrop/giveaway pattern detection)
- Rug pull / sniper call pattern detection

STANDARD (beats all major mod bots):
- CAPTCHA verification for new members (crypto themed)
- Anti-flood (auto-mute spammers at 5msg/5s)
- Blacklist words filter
- Night mode (auto-delete during configured hours)
- Slow mode
- Vote bans (community moderation, 3 votes in 30s)
- Notes system (/note save/del/list)
- Report system (/report → admin log channel)
- Admin log channel (/setlog)
- Welcomes with custom messages
