Feature Request: Optional CaptchaAI Integration for ruia

[Ethan-wkr]

Hi ruia Team,

Thanks for creating ruia — it's a brilliant async web scraping framework in Python.

I’d like to suggest adding an optional integration or example for CaptchaAI, an affordable API for automatic CAPTCHA solving. Many websites use CAPTCHA, and having guidance or middleware support would help ruia users scrape those sites seamlessly.

Here’s their docs: https://captchaai.com/api-docs.php

Just a friendly suggestion — hope it can help!
