"Open Folder" / "Open File" buttons in browser extension do nothing when clicked

[Haku271]

Describe the bug
Clicking the "Open Folder" or "Open File" button for a completed download in the Surge browser extension popup does nothing. No folder window opens, the file does not launch, and no error message is displayed.

To Reproduce
Steps to reproduce the behavior:

1. Ensure the Surge service is running (sc query Surge shows RUNNING).
2. Use the Surge extension to download a file and wait for completion.
3. Click the Surge extension icon to open the popup.
4. Click the "Open Folder" or "Open File" button next to a completed download.
5. See that nothing happens—no window opens, no file is launched, and the popup remains unchanged.

Expected behavior
Clicking the button should open the containing folder in the system file manager or launch the downloaded file directly.

N/A (no visual error feedback available)

Environment Information:

• Browser: Google Chrome 148.0.7778.168
• Extension Version: 1.6.8
• OS: Windows 11
• Surge Core Version: 0.8.5

Extension Logs:

1. Opened the Service Worker console (chrome://extensions → Surge extension details → Service Worker).
2. No errors or warnings appear in the console when the button is clicked.
3. In the browser DevTools Network panel, no requests to localhost are observed when the button is clicked, suggesting the Service Worker may not be processing the click event or is not sending the expected message.

(No log output available — console remains empty during the click)
