feat: QQ主动消息管道 + 戳一戳事件 + thinker提示词优化

- ProactiveTarget 结构体 + QQ目标正则解析（extractProactiveMessage 返回双值）
- storeThought 双路推送：platform消息 → platformMessagePusher，web消息 → messagePusher
- platform-bridge: SendProactive接口 + ProactiveSender + /api/v1/internal/send-proactive端点
- QQ戳一戳/notice事件 → noticeToUnified → ContentType "action"
- thinker提示词注入QQ频道上下文：群名称(群号)、活跃时间、trigger-aware引导
- SetBotUID/SetPlatformMessagePusher/AddOrUpdatePlatformChannel 方法
- ai-core source 增加 BotUID/GroupName，platform-bridge source 增加 bot_uid/group_name
- 支持 [CQ:at,qq=xxx] @提及标签自动拼接
