Subject: [PATCH] Add GitHub Actions CI/CD with multi-arch Docker builds

Replace the legacy Travis CI pipeline with GitHub Actions. The new
workflow uses Buildx + QEMU for multi-platform image builds
(amd64, arm64, armv7, armv5) and pushes to GHCR with GitVersion
semantic versioning. The Dockerfile is updated to use Buildx
platform args for native cross-compilation.
