Pull request overview
Adds a repository-specific .github/copilot-instructions.md to provide GitHub Copilot with context about how openvmm-deps is structured and how to build it (Docker multi-stage build, sysroots/packages, kernel workflow, and cgmanifest checks).
Changes:
- Introduces a Copilot instructions document covering architecture and key build scripts.
- Documents common Docker build commands and the cgmanifest sync check.
- Captures conventions for sysroots/packages and the kernel-version/config workflow.
💡 Add Copilot custom instructions for smarter, more guided reviews. Learn how to get started.
