fix: 修复 context_rewrite 工具调用问题并优化系统提示词

1. 修复 context_rewrite 导致的 API 错误

   - 删除错误的 tool 结果消息添加逻辑

   - 添加 context_compressed 标记让 AI 识别压缩结果

   - 将 context_rewrite 记录到 tool_calls 以便 TUI 显示

2. 优化系统提示词

   - 添加强制触发条件：每5次记忆工具调用必须调用 context_rewrite

   - 强化指代词处理规则：必须通过工作记忆链解析

   - 扩展时间指代词：添加刚刚

   - 更新执行检查清单
