GitHub App with Permanent Token

I already have a fully-working open-source project on GitHub. Your task is to rebuild that codebase into a fresh application and wire it up to a GitHub access token that never expires. PATs now have enforced expiry, so you may need to convert the logic to a GitHub App workflow, automate token refresh behind the scenes, or suggest any other approach that keeps authentication alive indefinitely—whatever reliably delivers hands-free access.

Alongside the updated code, I need a clear walkthrough of everything you changed so I can replicate the setup myself. A concise screen-share video is ideal, but a well-illustrated written guide is acceptable if recording isn’t practical.

Please highlight relevant experience with GitHub OAuth, GitHub Apps, or long-lived authentication in your bid. If you’ve tackled similar token-lifecycle challenges before, mention it—it will carry weight.

Deliverables:
• Modified repository (or fork) with the non-expiring GitHub authentication solution implemented
• Sample .env and deployment commands ready to run locally or on a VPS
• Step-by-step setup guide (video or document) showing how to regenerate the build from scratch and where to plug in secrets
