feat: 多智能体竞标调度系统 v1.0.0

核心组件：
- Orchestrator: 意图理解、任务拆分、竞标管理、结果验证
- Worker: 竞标任务、执行交付
- TaskBoard: 状态管理、信息存储
- BidEvaluator: 竞标评估算法
- ExecutionMonitor: 执行监控、超时处理
- LLMClient: 大模型接口调用

功能特性：
- 竞标机制：Agent主动竞争任务
- 动态调度：串行/并行任务智能调度
- 智能容错：超时切换、验证重试
- 质量保证：结果验证、历史追踪

Web界面：首页、请求列表、任务列表、Agent管理
API接口：请求/任务/Agent管理、测试接口
