Current Behavior

When navigating to URLs that contain dots (.) in the path, Capacitor's WebView treats them as file requests rather than SPA routes. This causes a 404 error instead of serving the index.html file for client-side routing.

For example:

• http://localhost/@username → Works (serves index.html)
• http://localhost/@user.name → Fails (404 - treats as file request)
• http://localhost/page.section → Fails (404 - treats as file request)

And shows console error in Xcode: ⚡️ WebView failed provisional navigation ⚡️ Error: The file “@user.name” couldn’t be opened because there is no such file.

And in Android, An error page is shown with Page is not available.

Expected Behavior

All non-asset URLs should serve index.html to allow the SPA router to handle routing, regardless of whether the URL contains dots.
