fix: Add proper GitHub token environment to pre-verification and issue creation steps

Resolves authentication failure in Pre-Discovery Verification step by:
- Adding GITHUB_TOKEN environment to pre-verification step
- Adding GITHUB_TOKEN environment to issue creation step
- Making auth status check non-failing to prevent workflow errors

Ensures workflow steps have proper GitHub CLI authentication.
