Kris 3cfb7dee25 refactor(bluebubbles): 重构并新增多项蓝泡泡适配器功能
本次提交对蓝泡泡适配器进行了多维度改进:
1. 新增缓存超限自动清理逻辑,防止内存溢出
2. 增强流式打字同步功能,增加超时自动停止逻辑
3. 重构markdown渲染逻辑,修复格式匹配问题并支持更多语法
4. 新增配置校验工具函数,增加streaming_mode和auth_strategy的合法性校验
5. 新增多项环境配置参数,完善配置项
6. 重构初始化流程,新增多个工具类实例
7. 优化TTS禁用逻辑,新增aiohttp依赖检查
8. 重构流式消息发送逻辑,整合打字指示器逻辑
9. 新增健康状态检查的问题检测功能
