Test: AI Workflow with GH_TOKEN Fix

[lenaxia]

Testing the issue-responder workflow after adding GH_TOKEN environment variable.

Expected behavior:

• Workflow should successfully authenticate using secrets.GITHUB_TOKEN
• AI should analyze this issue
• AI should add appropriate labels (question, P3, etc.)
• AI should post a welcoming comment

Previous issue:

• gh CLI was failing because GH_TOKEN environment variable was not set
• Added GH_TOKEN to workflow alongside GITHUB_TOKEN

This is test issue #3 to verify the authentication fix.
