Summary by CodeRabbit

• Chores
  • Added automated builds and publishing for demo images from designated demo branches.
  • Added safeguards to restrict image publishing to approved workflow actors.
  • Added branch-level concurrency controls to prevent redundant in-progress builds.
  • Published images are tagged with the source branch and commit for easier identification.

📝 Walkthrough

Walkthrough

Adds a GitHub Actions workflow that builds and publishes Docker images for demo-* branches. The workflow validates authorized actors, limits concurrent runs per branch, records image metadata, and logs out after execution.

Changes

Demo image publishing

Layer / File(s)	Summary
Demo image build and publishing .github/workflows/publish-demo-image.yml	The workflow runs for demo-* branch pushes, validates both workflow actors against IMAGE_PUBLISHERS, builds and pushes xinfinorg/devnet:<branch>, writes execution details to the job summary, and logs out of Docker.

Priority: ⬇️ Low

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: 🟡 Moderate · up to 89450

Publishing fails for valid demo branch names containing Docker-invalid tag characters, so demo images cannot be produced until the branch name is normalized for the image tag.

normalize GITHUB_REF_NAME into Docker-tag-safe characters, limit its length, and
append a short commit SHA suffix to avoid collisions while preserving the
existing repository and tag structure.
