feat(filter_bot_messages): 新增 filter_bot 开关，控制 bot 消息是否纳入分析

Fixes #205

默认排除 bot 自身发言（filter_bot_messages=True），可通过 /分析设置 filter_bot 切换。
修改涉及三层：
1. 配置层：ConfigManager getter/setter + _conf_schema.json 面板选项
2. 适配器层：BotManager 传入配置，OneBotAdapter.fetch_messages 认 switch
3. 分析层：clean_messages 和 analyze_user_activity 的 bot_self_ids 受 switch 控制
