✨ feat(im)：文本气泡 @ 高亮支持点击 + URL 自动识别成可点击链接

- @ 段：群消息按 atUserIds 反查群成员，候选 name 兼容历史字面量（真实昵称 / 好友备注 / 群自定义昵称），displayName 统一收敛到 nickname，让历史消息也能渲染成 @真实昵称；@ 段点击弹 UserInfoCard
- @所有人：注入 IM_AT_ALL_USER_ID 虚拟候选，对齐微信 PC 仅高亮配色不挂点击
- 同名歧义：同字面量对应多个 userId 时标记 ambiguous，parser 整段消费成普通文本，避免错绑用户
- URL：识别 http(s) / www. 起头链接，<a target="_blank"> 新标签打开；默认补 https://
- TipSegment 加 link 变体作为统一文本片段类型，TEXT 气泡与灰条 tip 共用 TipSegments 组件渲染
- MessageInput @ token 文本统一用真实昵称，不再掺好友备注 / 群自定义昵称
