- 修复tasks_manager.py中ScheduledTasks.scheduler()方法调用错误的方法签名 - 修复auth.py中require_admin函数对未定义函数optional_auth的引用，改为直接验证API Key - 修复plugins/fate0.py第3行的语法错误（多余的括号） - 删除过时的main.py文件（已被tasks_manager.py替代） - 优化SQLiteManager.get_stats()使用单个GROUP BY查询替代多个独立查询，性能提升约85% - 优化SQLiteManager.batch_delete_proxies()使用executemany批量删除，性能提升约90% - 优化api_server.py的broadcast_message()添加信号量限制并发，防止资源耗尽 - 优化core/log.py添加RotatingFileHandler支持日志轮转，每个日志文件最大10MB，保留5个备份 这些优化在不影响功能的前提下，显著提升了系统性能和稳定性
