docs(README): update community helper section with details about mhrv…

[ardalan-ab]

Description

This PR adds a small "Community Helpers" section to the README linking to the external extension repository:

• https://github.com/ardalan-ab/mhrv-helper-extension

The extension is now maintained separately to keep the main repository focused on the proxy + Apps Script core while still making the helper tool discoverable for users.

Since the previous review, the extension repository also includes:

• a CI sync check to ensure chrome-extension/Code.gs stays synchronized with assets/apps_script/Code.gs
• additional basic test coverage improvements
• a version-check mechanism for extension updates

I’m also open to the extension being published under your account for consistency and user trust, while still continuing maintenance and contribution on my side.

This follows the direction discussed in the earlier PR review.

ترجمه فارسی

این PR یک بخش کوچک با عنوان "Community Helpers" به README اضافه می‌کند که به ریپازیتوری جداگانه افزونه لینک می‌دهد:

• https://github.com/ardalan-ab/mhrv-helper-extension

افزونه اکنون به‌صورت جداگانه نگهداری می‌شود تا ریپازیتوری اصلی روی هسته پروژه (proxy و Apps Script) متمرکز باقی بماند و در عین حال این ابزار کمکی همچنان برای کاربران قابل دسترس باشد.

همچنین بعد از ریویوی قبلی، موارد زیر به ریپازیتوری افزونه اضافه شده‌اند:

• CI sync check برای اطمینان از همگام بودن chrome-extension/Code.gs و assets/apps_script/Code.gs
• بهبود پوشش تست‌های اولیه
• قابلیت بررسی نسخه برای اطلاع از جدیدترین نسخه افزونه

همچنین من مشکلی ندارم که افزونه برای هماهنگی بیشتر و اعتماد کاربران تحت اکانت شما منتشر شود، در حالی که همچنان نگهداری و توسعه آن را ادامه می‌دهم.

این PR بر اساس مسیر پیشنهادی در ریویوی قبلی ایجاد شده است.

Please make sure the Persian text starts with Persian alphabet, otherwise the right to left is not respected. Maybe rephrase some of the sentences.

Thank you for the review. I made the necessary changes. Could you please take another look? Let me know if there's anything else that needs to be adjusted

Thanks for moving the helper-extension direction toward an external repo instead of vendoring the whole extension here.

I would like one cleanup before merging this README change: please avoid listing the same helper twice in the first screen plus a full section below. The current diff adds:

• a top-of-README bold one-liner in English,
• a full English Community helpers section,
• a top-of-Persian bold one-liner,
• a full Persian ابزارهای جامعه section.

That is a lot of visual weight for an optional third-party helper, and it can read like an official dependency. I think the better shape is:

• one Community helpers / ابزارهای جامعه section only,
• include a clear note that it is optional and third-party maintained,
• link README + usage docs from there,
• no top banner above the quick start.

Once the duplication is trimmed, this is mergeable as a docs-only discoverability improvement.

removed duplicate helper-extension references from the top sections and consolidated them into a single Community helpers / ابزارهای جامعه section. The wording was also adjusted to clearly mark it as optional and third-party maintained.

One quick question for clarification (as discussed earlier): would you prefer the helper extension to be published to the Chrome Web Store at some point, or should it remain as a GitHub-distributed tool only?
Also, I don’t have a Chrome Web Store developer account—if you ever decide to publish it, I’m fine if it’s done under your account/name.
