The container build fails with 'unknown instruction: curl' on line 6, which
suggests the Dockerfile continuation characters or line endings may be
malformed. Add defensive logging to diagnose:
- Force newline='\n' in all write_text calls in build_image for consistent
Unix line endings regardless of platform
- Log compiled Dockerfile and entrypoint content at INFO/DEBUG level
- Log Dockerfile byte count when written
This will let us see exactly what Docker is receiving in the next build attempt.
