feat: Add SENTINEL Deep Threat Scanner (9-collection security analysis)

- Created sentinel_deep.py with comprehensive threat scanning
- Analyzes 9 security collections: contract health, liquidity security,
rug imminence, MEV exposure, supply manipulation, fee manipulation,
wash trading, deployer history, social intelligence
- Returns threat score 0-100 with per-collection breakdown
- Added x402 router endpoint at /api/v1/x402-tools/sentinel_deep
- Added test file with async pytest tests

+SENTINEL Deep Threat Scanner
+=============================
+Comprehensive on-chain threat detection combining 9 security collections into one
+unified risk assessment. The "security SIEM" for DeFi tokens.
+
+Collections analyzed:
+  1. CONTRACT HEALTH — Honeypot traps, ownership risks, upgrade vulnerabilities
+  2. LIQUIDITY SECURITY — LP lock status, withdrawal risks, single-sided pools
+  3. RUG IMMINENCE — Early warning signals for imminent rug pulls
+  4. MEV EXPOSURE — Sandwich attack risk, frontrunning exposure
+  5. SUPPLY MANIPULATION — Bundled launches, insider distributions
+  6. FEE MANIPULATION — Hidden taxes, dynamic fees, sell traps
+  7. WASH TRADING — Artificial volume, circular trades, fake activity
+  8. DEPLOYER HISTORY — Previous scams, funding patterns, risk trajectory
+  9. SOCIAL INTELLIGENCE — Shill campaigns, hype spikes, telegram analysis
+
+Architecture:
+  - Modular design: Each collection is a separate analyzer
+  - Confidence-weighted scoring: Each signal has data confidence factor
+  - Multi-chain support: EVM (Ethereum, BSC, Base, Arbitrum, Polygon) + Solana
+  - Evidence-first: Every finding includes concrete on-chain evidence
+  - Integration ready: Works with existing RMI detectors

+Tier: Premium ($0.10)
