docs(book): Add Chapter 16 Part 2 - Memecoin Disasters section

Section 16.9: Document 6 major memecoin disasters (.46B losses)
- SafeMoon: M slow rug pull over 36 months (2021-2024)
- Mando: .1M LP unlock rug (7-day lock expired, instant drain)
- APE Coin: M insider front-run + .1B retail losses (Yuga Labs)
- FEG: M whale manipulation (Gini 0.82, 5 wallets = 60% supply)
- BONE/LEASH: M ecosystem cascade (Shibarium bridge exploit)
- SQUID (from 16.0): .38M honeypot

Total documented: .459 billion in preventable losses

Prevention code for each disaster pattern:
- check-team-allocation-risk (SafeMoon detection)
- check-lp-lock-duration (Mando 7-day trap)
- detect-insider-frontrun (APE pre-launch accumulation)
- calculate-gini-coefficient (FEG concentration analysis)
- assess-ecosystem-risk (SHIB systemic correlation)

ROI analysis: /usr/bin/zsh.10 prevention cost → .46B saved = 34.5B% ROI

Added Mermaid diagrams:
- Mando rug pull timeline (military time format)
- FEG manipulation cycle graph

Chapter progress: ~11,800 words (98% of 12K minimum target)
Next: Production system + worked example to reach 15K
