Code Review
This PR significantly refactors the Markdown rendering logic and AI streaming response handling, extracting them into markdown-components.tsx and use-ai-stream.ts respectively. This greatly enhances code readability, maintainability, and reusability, while also fixing Markdown inline code rendering issues. However, a critical security vulnerability has been identified in the custom link components, which render user-supplied URLs directly into the href attribute of <a> tags without proper sanitization, making the application susceptible to Cross-Site Scripting (XSS) attacks via javascript: URIs. Remediation requires implementing a strict allow-list for URI protocols. Furthermore, there are suggestions for improving type safety and performance optimization, particularly within the newly created markdown-components.tsx and use-ai-stream.ts files.

为了优化性能并遵循 React Hooks 的最佳实践，建议使用 useCallback 来记忆化传递给 useAIStream 的 onUpdate 和 onComplete 回调函数。这可以防止它们在每次父组件渲染时都重新创建，从而避免 useAIStream hook 内部不必要的重渲染。
这个建议同时适用于 useAIContinue 和 useAIPolish 两个 Hook。
const onUpdate = useCallback(
(response: string) => {
const pos = getPos();
if (pos !== undefined) {
editor.commands.updateContinueContent(pos, response);
}
},
[editor, getPos],
);
const onComplete = useCallback(
(response: string) => {
updateAttributes({ state: 'display', response });
},
[updateAttributes],
);
const stream = useAIStream({
onUpdate,
onComplete,
});
