✨ Highlight Matching Tags

该 issue 未列出任何文件、测试或入口点。首先定位编辑器中负责标签解析、光标匹配、高亮显示和编辑同步的组件；当对于所描述的光标位置，相匹配的开始标签和结束标签都被高亮显示，并且在编辑名称时仍保持同步，即视为完成。

Description

We want to enhance tag-matching behavior in markup languages such as HTML, XML, and JSX by highlighting matching tags based on cursor position. This feature is inspired by bracket matching in Xcode, where matching brackets are highlighted based on cursor placement.

When the cursor is placed within a tag, the corresponding opening or closing tag should be highlighted. Additionally, if any tag name is modified in either the beginning or end tag, the matching tag should update to reflect the change.

Behavior Examples

In the following examples, | represents the cursor position, and underlined text represents the highlighted matching tags:

• <|div class="wrapper">Hello world!</div>
• <div| class="wrapper">Hello world!</div>
• <div class="wrapper">|Hello world!</div>
• <div class="wrapper">Hello world!<|/div>
• <div class="wrapper">Hello world!</div|>
• <div class="wrapper">Hello world!</div>|

Requirements

1. Cursor-Based Tag Matching:

   • When the cursor is within a tag name, either at the opening or closing tag, the corresponding tag should be highlighted.

2. Tag Synchronization:

   • When a tag name is edited, the matching tag should update to reflect the change in real-time, ensuring that both tags are always in sync.

3. Highlight Behavior:

   • Highlighting should clearly indicate the matching tag, using a distinct visual style (e.g., underline or color change) for both the opening and closing tags to enhance visibility.

This feature will improve the editing experience by making it easier to identify matching tags, reducing errors in nested or complex structures.
