herel 4482c4041e feat(docker): optimize build caching and fix binary path
- Copy Cargo files first to leverage Docker layer caching
- Build dependencies separately before copying source code
- Use cache mounts for cargo registry to speed up builds
- Fix binary path in final stage from cargo bin to target release
