- Introduced a new script (inject.js) to override the fetch and XMLHttpRequest methods to capture requests to the "getgeoidx" endpoint. - Captured request body and URL, and sent the data to the extension via postMessage. - Added intercept.js to inject the new script into the page and listen for messages to forward captured data to the extension.
