fix: 死锁修复、管理员权限集中管控、群聊频率控制、表情映射修复

thinker.go: 移除所有 defer t.muUnlock() 持锁跨阻塞调用的模式，消除8处死锁点
- performThink: defer→立即解锁，LLM调用不再持锁
- lightThinkLoop: defer在for循环内→第2次迭代自死锁
- resetSilenceTimer: defer持锁调performThink
- UpdatePresence: defer持锁调time.Sleep+performThink
- storeThought: defer+panic→锁泄露; 移除extractProactiveMessage嵌套锁

is_admin三层防御:
- synthesizer: 系统提示词注入管理员/非管理员身份标签
- iot_provider: 非管理员直接拒绝IoT操作
- plugin-manager: ToolDefinition.AdminOnly自动拦截，集中管控

群聊优化:
- group_ambient: 强化审查指令，【不发送】自审查标签
- 群聊间隔4s→3s，最多2条/轮
- 工具失败也推跟进消息，避免沉默

平台桥接:
- 日志文件名使用适配器唯一标识符(ConfigName)
- QQ表情映射替换为官方116条目数据
- CQ表情保留名称/ID
