Upstream defaults all text files to CRLF (Windows-only dev). On Linux,
bash refuses to execute shell scripts with CRLF line endings, which
blocked the v0.1.0 pre-push hook with 'env: »bash\r«: nicht gefunden'.
Override the default for *.sh, .githooks/*, and scripts/* to eol=lf
so the hook + preflight runs cleanly on both Linux and Windows.
