feat: add Fear Hunter — Sentiment Dislocation Alpha v2.0

[0xCaptain888]

New Skill: 恐惧猎手 · Fear Hunter

A contrarian trading skill based on Fear & Greed Index × Funding Rate dislocation.

Core Logic

	Funding < -0.01% (shorts crowded)	Funding > 0.05% (longs crowded)
F&G < 25 (Fear)	✅ Double Fear → LONG	⚠️ Conflicting → Skip
F&G > 75 (Greed)	⚠️ Conflicting → Skip	✅ Double Greed → SHORT

Key Features

• Three-layer filter: Sentiment scan → Funding rate dislocation → Technical confirmation
• ATR-based position sizing: 2% risk per trade, stop loss = 1.5×ATR
• Small account friendly: Designed for 100–1,000 USDT accounts
• Targets: BTC-USDT-SWAP (primary), ETH-USDT-SWAP (secondary)
• Leverage cap: BTC 3x, ETH 2x

Validation

• 30-day backtest: 3 trades, ~+5% cumulative return, <1% max drawdown
• Live demo trade records included (BTC long + ETH/SOL skip decisions)
• 83% of time in cash — only trades at extreme dislocations

Risk Control

• Per-trade max loss: 2%
• Daily drawdown pause: 4% → 8h cooldown
• Weekly drawdown pause: 8% → pause until next week
• 3 consecutive losses → auto position reduction
