refactor: move Docker files to deploy/docker/

Move all 6 Docker files (Dockerfile, Dockerfile.gpu, Dockerfile.gpu.rocm,
Dockerfile.sandbox, docker-compose.yml, docker-compose.gpu.rocm.yml) from
the project root into deploy/docker/ to reduce root-level clutter. Update
build context paths in both docker-compose files to point back to the
project root (../..) so Docker builds continue to work correctly.
