希望添加对html标签的支持

从Typecho迁移至此，隔壁的编辑器支持Markdown/html混排，可以使用<p>等标签嵌入外部播放器，更改文字颜色，迁移至Halo后使用byteMD编辑器无法使用这类标签
希望能添加对此类标签的支持，推倒重写太困难了www

The issue names the ByteMD editor and requests mixed Markdown/HTML support for and <p> tags, but provides no file or test location. Start by locating how the plugin parses or sanitizes HTML, and clarify the security expectations. Done means the reported tags work alongside Markdown without breaking existing editing behavior, with coverage for the examples.
