Add CaptchaAI as a 2Captcha-compatible solving option (happy to contribute a guide)

Hi Naibo — big fan of EasySpider. I love that you already document a captcha path (the CapSolver guide), and I'd like to offer your users a second option — not to replace anything, just another choice.

I'm Bassem from CaptchaAI. CaptchaAI is 2Captcha-API-compatible (same in.php / res.php flow), so it drops straight into the same EasySpider patterns your CapSolver guide already covers — an Execute System Command node calling a small Python script, Custom Action JS nodes, or editing easyspider_executestage.py. It solves reCAPTCHA v2/v3 + Enterprise, Cloudflare Turnstile, GeeTest, and image/OCR. It's priced by concurrent threads (unlimited solves) rather than per-solve, so it gets cheap at scale for high-volume scraping users.

I'd be glad to contribute a ready-to-publish guide — "How to Solve Captcha in EasySpider with CaptchaAI" — mirroring the structure of your CapSolver doc (already drafted, with a working captcha_solver.py). Yours to edit/merge.

Want me to open a PR with the guide? No pressure either way — even just listing CaptchaAI as an alternative option helps your users. Thanks for building EasySpider!
