Summary

Syncing documentation for cloudflare/sandbox-sdk#245: Remove multi-arch Docker image support

This PR updates documentation to reflect that Sandbox SDK now builds Docker images for linux/amd64 only to match Cloudflare's production container runtime.

Changes

  • Docker setup partial: Added architecture compatibility section explaining amd64-only builds and automatic emulation on ARM Macs
  • Dockerfile reference: Updated base image description to clarify linux/amd64 architecture and added note about dev/prod parity

Key points

  • Images are built for linux/amd64 only to ensure dev/prod parity
  • ARM Mac users will automatically use emulation (Rosetta/QEMU)
  • This prevents architecture-specific bugs caused by Docker selecting ARM64 variants on ARM hosts
