uppifyagency/ghostmap ? reverse-engineered prompt

Build me a Chrome extension that helps me turn Google Maps search results into a clean CSV of business leads.

I want to open Google Maps, search for something like plumbers in London or restaurants in Milan, then click the extension and have it capture the businesses that are already loaded on the page. It should save useful details like name, phone, website, email, address, rating, review count, opening hours, category, and location, and for Italian businesses it should also try to pull the VAT number.

Make it run locally in the browser, with no API key and no external server. I want a simple side panel where I can start and stop the capture, see progress, and export the results as a CSV that opens nicely in Excel or Google Sheets. If possible, also add a way to discover emails from the business website and a webhook export option. Keep it private, fast, and easy to use, and look up current Chrome extension docs online if you need to.
