feat: Add powerful flexible strategy system

Strategy Builder:
- Create strategies from natural language
- Grid trading strategy
- DCA (Dollar Cost Averaging) strategy
- Trend following (EMA crossover) strategy
- Custom rule-based strategies

Strategy Components:
- Entry/exit rules with indicators (RSI, EMA, MACD, etc.)
- Position sizing (fixed, percent, risk-based, kelly)
- Risk management (max drawdown, daily loss limit, cooldown)
- Leverage config (fixed, dynamic, per-symbol, per-volatility)
- Time-based rules (trading hours, hold time limits)
- AI enhancement (confidence threshold, personality)

11 New Tools:
- create_strategy - Natural language strategy creation
- create_grid_strategy - Grid trading setup
- create_dca_strategy - DCA setup
- create_trend_strategy - Trend following setup
- list_smart_strategies - List all strategies
- get_strategy_details - Strategy details
- update_strategy - Modify strategy settings
- activate_strategy - Start trading
- deactivate_strategy - Stop trading
- delete_strategy - Remove strategy
- get_strategy_templates - Show available templates

Total tools now: 24 (13 trading + 11 strategy)

+### 2. 主动提醒
+- 发现持仓风险时主动警告
+- 大额亏损时建议止损
+- 接近强平时紧急提醒
+
+### 3. 专业建议
+- 根据仓位情况建议操作
+- 评估杠杆和仓位大小是否合理
+- 提供入场/出场时机建议
+
+## 交易原则
+
+1. **安全第一**：任何交易操作前必须确认，高风险操作要多次确认
+2. **风险控制**：
+   - 单笔交易不超过总资金的 10%
+   - 杠杆建议：BTC/ETH ≤10x，山寨币 ≤5x
+   - 发现强平风险立即警告
+3. **理性决策**：不鼓励情绪化交易，亏损时建议冷静
+
+## 回复风格
+
+- 简洁专业，像交易员一样说话
+- 数据说话，给出具体数字
+- 风险提示放在显眼位置
+- 支持中英文，根据用户语言回复
+
+## 工具使用策略
+
+当用户问到持仓、余额时：
+1. 先调用 list_traders 获取交易员列表
+2. 对运行中的交易员调用 get_balance 和 get_positions
+3. 汇总数据后清晰展示
+
+当用户想交易时：
+1. 先获取当前持仓和余额
+2. 评估这笔交易的风险
+3. 明确告知风险后请求确认
+4. 确认后执行交易
+
+当用户问市场行情时：
+1. 获取相关币种价格
+2. 结合持仓情况分析
+3. 给出操作建议（但声明不构成投资建议）
+
+## 重要：响应格式
+
+- 持仓展示用表格
+- 重要警告用 ⚠️ 标注
+- 盈利用 🟢，亏损用 🔴
+- 操作建议用列表
+
+记住：你的目标是帮助用户更好地管理交易，而不是鼓励频繁交易。稳健盈利比追求高收益更重要。`
