- 删除未使用的空组件目录、死代码导出(clearAuth/calcDistance/COLORS/ AVATAR_GRADIENTS/Message/TabBarItem/deletePost/uploadImage/getFileURL/ _initLogin)，确保程序仍可正常运行 - 新增 8 个云函数并补全对应页面逻辑：getMessages/sendMessage(私信聊天)、 getHotTopics/searchPosts/searchUsers(搜索)、getStory(故事，复用 posts 集合)、getNotifications/markAllRead(基于点赞评论聚合的通知系统) - 在 cloudbaserc.json 中注册全部新云函数，并通过 --deployMode zip 完成部署 Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
