添加全局协作规约功能

新功能：
- 新增 global_collaboration_rules 表
- POST /api/rules/global - 设置全局规约
- GET /api/rules/global - 获取全局规约
- 智能体领取任务时同时收到全局规约和项目规约

规约层级：
1. 全局规约 - 适用于所有项目和智能体
2. 项目规约 - 仅适用于特定项目

智能体领取任务时的响应示例：
{
  "collaboration_rules": {
    "global_rules": "全局规约内容",
    "project_rules": "项目规约内容"
  }
}
