`*.sh text eol=lf` reaches new clones only. A clone checked out before the
rule keeps scripts/build-quic-native.sh with carriage returns after pulling,
because the blob did not change: git neither rewrites the file nor reports it
modified, and the container still dies on the interpreter `bash\r`.
The README now gives the repair where a newcomer meets the container path,
and .gitattributes points to it. Verified on clones made at 367c9bc and moved
to c25de5a, from Git Bash and from Windows PowerShell 5.1: 109 CR bytes
before, none after, status clean. The line uses `;` so it runs in both.
