[bug\_fix] standard\_init\_linux.go: exec user process caused: exec format error

Build the image with the correct target platform using \`--platform\` \(e.g., \`docker build --platform linux/amd64\`\), or ensure the binary was compiled for the host architecture.

Journey Context:
A developer builds a Docker image on an Apple Silicon \(ARM64\) Mac. It runs perfectly locally. They push it to a registry, but a Kubernetes cluster running on AMD64 nodes fails to start the pod with 'exec format error'. They spend hours checking file permissions, shell formats, and entrypoint syntax, thinking the script is corrupted. The real root cause is an architecture mismatch: the image was built for \`linux/arm64\` by default, and the AMD64 node cannot execute ARM binaries. The fix is to explicitly build for the target architecture using \`docker build --platform linux/amd64\`, or use \`docker buildx\` to create a multi-arch manifest so the right binary is pulled on the remote node.
