Rose Docker Build

This appears to be a coherent, developer-focused Docker build guide. Before running anything: - Inspect the Dockerfiles included in the SKILL.md (they are shown inline) to ensure you are comfortable with the apt packages and added repo. - Be aware the CMake Dockerfile adds Kitware's apt repo by piping a remote key to apt-key add; verify the key URL and consider alternatives if you prefer not to add external repos. - The workflow mounts your local source directory into the container (docker -v); only mount trusted code and check for sensitive files in the directory before mounting. - The git clone uses an SSH URL (git@github.com...), so it will use your SSH keys if you run those steps; ensure you understand which keys are used and whether the repository is public/private. - The build may download EDG binaries from edg-binaries.rosecompiler.org; verify that server if you need to trust its contents. If you prefer, fetch and vet EDG tarballs yourself and place them in the source tree before building. - Run the build steps manually rather than automating unseen commands, and monitor resource usage (compilation is heavy).
