Added docker-ignore (#108)

* Added docker-ignore

* ops(docker): publish Claw3D images from main.

Add a GHCR publishing workflow and expose a health endpoint so Fly deployments can build and pass runtime health checks.

Made-with: Cursor

* ops(docker): publish branch preview images.

Tag non-main branch builds with the branch name so test deployments can use GHCR images before merging to main.

Made-with: Cursor
