feat(info): 信息面板 UI 重做 + 双向批量关联 + 代码块内全选复制

1. 信息面板 UI 重做：设计 token 统一、lucide 图标、分区小节、星标/标签/关联 chip 化
2. 关联文档升级：新增 doc:link-batch IPC，A↔B 双向写入 links；面板支持快速双向关联 + 批量勾选关联/解除
3. 代码块内全选复制：Ctrl+A 在代码块内仅全选该代码块（TyporaKeys selectInsideCodeBlock），Ctrl+C 复制纯代码；代码块内 Ctrl+V 按纯文本粘贴
4. 修复 React error #62：btn 改为函数后遗漏 style={btn} 裸用，导致 render 期间更新
