Add health check, backtest, correlation tracker, wallet setup, and skills registry

New scripts:
- health_check.py: one-command session-start workflow (portfolio + live prices +
  drawdown + stop losses → GREEN/YELLOW/RED status)
- backtest.py: performance analysis with live-readiness assessment against
  CLAUDE.md prerequisites (20+ trades, >55% win rate, Sharpe >0.5)
- correlation_tracker.py: detects hidden correlated exposure in portfolio
  (e.g., 3 insider-trading bets = one cluster)
- setup_wallet.py: burner wallet creation, env var verification, on-chain
  balance check for live trading setup

Also adds:
- .env.example template for live trading configuration
- .well-known/skills/index.json for Agent Skills registry discovery
- Updated SKILL.md files documenting new scripts
- .gitignore entries for .env, .polymarket-live/, and key files

+### 4. Correlation Tracker (`scripts/correlation_tracker.py`)
+
+Detect hidden correlated exposure in your portfolio:
+
+- Groups positions by topic (crypto, politics, sports, geopolitics, etc.)
+- Detects shared qualifiers ("insider trading", "FIFA World Cup", etc.)
+- Warns when correlated clusters exceed concentration limits
+- Outputs diversification score (0-100)
