Build on the native host arch (--platform=$BUILDPLATFORM) and cross-compile the static binary per target via buildx-provided TARGETOS/TARGETARCH, so `make docker-build` with REGISTRY set produces linux/amd64 + linux/arm64 images without emulating the Go toolchain under QEMU. Also correct the CMD comment to the real env var (NOTIFIER_SERVER_MODE). Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
