Potential fix for code scanning alert no. 1: Incomplete URL substring sanitization

[sogik]

Potential fix for https://github.com/sogik/ZTalon/security/code-scanning/1

To address the flagged issue, the URL should be properly parsed using the urllib.parse module to extract the hostname. Instead of checking if "github.com" is a substring of the URL, we should verify that the hostname of the parsed URL matches the trusted domain github.com. This approach eliminates the risk of unintended matches caused by substring checks.

Detailed Steps:

1. Parse the URL using urllib.parse.urlparse.
2. Extract the hostname from the parsed URL.
3. Compare the hostname directly with github.com.

This fix ensures that only valid GitHub URLs pass the check, addressing the CodeQL warning.
