守门员基础版 + 进阶意图层 + 关键帧技能

守门员基础版：
- 1号门将从外场逻辑中分流，具备 HOME/INTERCEPT/CLEAR/PENALTY_READY/RECOVER 状态机
- 门线封角、横移巡逻、禁区内拦截、边路清球、点球站位
- 只依赖 Walk/Neutral/GetUp，不引入真实 catch 或 RL 扑救

守门员进阶意图层：
- GoalieSet 保留为生产姿态
- BLOCK_LEFT/BLOCK_RIGHT 降为意图层，不作为正式比赛动作
- CATCH_* 骨架与计时保留，不发真实协议
- GoalieBlock RL 占位接口预留

新增关键帧技能：
- GoalieSet（生产）、LowBlockLeft/LowBlockRight（实验）
- 注册到 BehaviorManager，has_skill() 接口新增

MonitorClient 改动：
- place_player 支持 yaw 参数
