Add debug logging to see what environment variables are available

- Show all token-related environment variables
- Check specific variables: ACCESS_TOKEN, FORGEJO_TOKEN, GITHUB_TOKEN
- This will help diagnose why the secret isn't being detected
- Should reveal if it's a secret access issue or variable naming issue
