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

Build the image for the correct target architecture using the --platform flag \(e.g., docker build --platform linux/amd64\), or fix the line endings of the entrypoint script from Windows CRLF to Unix LF.

Journey Context:
A developer builds a Docker image on an Apple Silicon \(ARM64\) Mac and pushes it to a registry. A Kubernetes cluster running on AMD64 Linux nodes pulls the image, and the pod crashes with exec format error. The developer assumes the binary is corrupted or the registry served a bad layer, wasting time re-pushing and verifying checksums. In another scenario, a developer writes an entrypoint.sh script on Windows and builds it into a Linux container, hitting the exact same error. The root cause in the first case is an architecture mismatch \(ARM binary executed on AMD64\). In the second case, the Windows CRLF line endings cause the Linux kernel to look for an interpreter at /bin/bash , which does not exist. Specifying --platform forces Docker to emulate the target architecture via QEMU, and converting line endings to LF ensures the Unix kernel can parse the script shebang correctly.
