Subject: [PATCH] feat: add Docker build workflow

Adds automated Docker image builds using shared workflow:
- Builds for CUDA applications (linux/amd64 only)
- Pushes to GHCR (ghcr.io) and Docker Hub
- Smart tagging: latest, semver, SHA, branch names
- Automated on push to main, tags, and PRs

Requires DOCKERHUB_TOKEN secret to be configured.
