[bug] Infinite loop in scope::fs::push_pattern

[alexmoon]

Describe the bug

On Windows, calling tauri::scope::fs::push_pattern with a pattern of "\\?\**" results in an infinite loop attempting to create the canonicalized path.

Reproduction

1. In an app's capabilities JSON add to the permissions array:

{ "identifier": "fs:scope", "allow": ["\\\\?\\**"] }

2. Perform any fs API call from the frontend. The backend will lock up in an infinite loop when creating the Scope.

Expected behavior

push_pattern should either return an error or process the pattern successfully.
