deploy.sh and the other scripts run on the Linux deploy host and in
Docker. A CRLF checkout breaks them with "bad interpreter: bash\r".
The committed blobs are already LF, but nothing guaranteed it against a
host with core.autocrlf=true. `*.sh text eol=lf` makes it explicit.
Verified: git ls-files --eol shows attr/text eol=lf on all .sh files;
renormalize produced no index churn (already LF).
