A major update: advanced reseller detection, Google Sheets scanning, more agents, Russian and Bulgarian support, and a much easier extension to use day to day.

New:
- Advanced Reseller Detection - a smarter check for spotting resellers and scammer sellers.
- Google Sheets scan - sign in with Google, scan every seller link in a spreadsheet at once, and get a score, a seller breakdown, and a shareable card.
- Added OopBuy, Litbuy, GTBuy, EastMallBuy, USFans, Itaobuy, Rizzitgo, and Fansbuy agents.
- Added Russian and Bulgarian language support.
- QC Compare - place QC photos on a canvas next to the real item photos to inspect them side by side.
- Preview item photos directly from the extension, no need to open the source page.

Improved:
- Several polish fixes to the sidebar's seller panel.
- Update notices redesigned with a clearer visual style.
- A lot of UI tweaks across the extension, making it a whole lot easier to use.

Fixed:
- Registration prompts no longer show a fake welcome credit for agents that only offer a percentage discount.
- Yupoo's own category navigation no longer gets mistakenly labeled as a seller link.
