Pull request overview
This PR adds official Docker image support with improved build caching using cargo-chef, addressing issue #829. The implementation uses a multi-stage build process that separates dependency compilation from the final application build, enabling better layer caching and faster rebuilds.
Key Changes:
- Refactored Dockerfile to use cargo-chef for dependency caching with a three-stage build (planner, builder, runtime)
- Added GitHub Actions workflow job to build and publish multi-platform Docker images (amd64/arm64) to GitHub Container Registry
- Configured automated Docker image tagging with semantic versioning
