Subject: [PATCH] fix: strip CRLF from shell scripts during Docker build

Safety net for Windows developers whose git config (core.autocrlf=true)
converts LF to CRLF on checkout. Even with .gitattributes forcing eol=lf,
some git configurations can still produce CRLF working copies. The sed
pass after COPY ensures start.sh and other scripts always have Unix
line endings inside the container.
