增强重复事件处理和TBD管理 v3.7

主要改进：
- 改进TBD比赛ID生成：TBD vs TBD使用时间戳生成唯一ID，避免重复
- 自动删除被取代的TBD事件：当队伍确定后删除对应占位符
- 重复比赛清理：优先保留已完成的比赛，删除未完成的重复
- 增强重复检测：按30分钟时间窗口分组，自动清理同时间重复

修复的问题：
- 修复了XG vs TBD等重复占位符事件问题
- 修复了NGX vs Liquid等比赛的重复记录问题
- 改进了过期TBD事件的清理逻辑

 # Changelog
 
+## v3.7 - 2025-09-08 - 增强重复事件处理和TBD管理
+- **改进TBD比赛ID生成**：
+  - TBD vs TBD比赛现在使用时间戳生成唯一ID，避免重复创建
+  - 普通比赛继续使用队伍+锦标赛组合生成ID
+- **自动删除被取代的TBD事件**：
+  - 当同一时间段存在确定的比赛时，自动删除对应的TBD占位符
+  - 例如：XG vs Tundra确定后，自动删除XG vs TBD事件
+  - 使用30分钟时间窗口匹配相近时间的事件
+- **重复比赛清理功能**：
+  - 自动检测同一天同队伍的重复比赛
+  - 优先保留已完成的比赛，删除未完成的重复事件
+  - 修复了NGX vs Liquid等比赛的重复问题
+- **增强的重复事件检测**：
+  - 按30分钟时间窗口分组事件
+  - 自动删除同时间的重复TBD事件
+  - 改进了过期TBD事件的清理逻辑
+- **改进TBD事件更新逻辑**：
+  - 只在队伍确定时才尝试更新TBD事件（避免TBD vs TBD互相匹配）
+  - 保持1小时的时间窗口用于TBD事件匹配
+
 ## v3.6 - 改进TBD比赛处理机制
 - **放宽TBD比赛时间匹配条件**：
   - 将TBD事件匹配的时间窗口从5分钟扩大到1小时
