Pull Request Overview

This PR adds JSDoc comments throughout the plugin-markdown-ext source and polishes both Chinese and English documentation for the plugin, including a minor update to copilot instruction formatting.

• Added JSDoc blocks to options.ts, markdownExtPlugin.ts, vPre.ts, utils.ts, and component.ts to improve inline API documentation.
• Refined wording and list formatting in Chinese (docs/zh/plugins/markdown/markdown-ext.md) and English (docs/plugins/markdown/markdown-ext.md) docs for consistency.
• Updated guidance in .github/copilot-instructions.md for when to use inline vs. paragraph descriptions.
