Updates build configuration for multi-platform support

Configures the build process to support multiple platforms (Linux, Darwin, Windows) and architectures (amd64, arm64).

Disables CGO to simplify cross-compilation.

Updates Docker image creation to produce separate images for amd64 and arm64, and creates manifest lists for `latest` and versioned tags.
