Subject: [PATCH] Add .gitattributes: *.sh text eol=lf for Windows clones

Windows clones default to core.autocrlf=true, which checks out CRLF into
*.sh working copies even though the committed blobs are byte-clean. The
shebang then dies with "env: 'bash\r': No such file or directory"
(exit 127), which read like a broken script rather than a line-ending
artifact. Assert LF for all shell scripts at the repo root so every
Windows clone gets clean scripts/gate.sh, data/icon/generate.sh and
data/shader/output.sh.

Closes #19

+# Force LF line endings for shell scripts.
+# Without this, Windows clones (git's core.autocrlf=true default) check out
+# CRLF and the shebang dies with:  /usr/bin/env: 'bash\r': No such file or directory  (exit 127)
+# Keep every *.sh blob byte-clean; existing clones need a forced re-checkout
+# (rm -f .git/index && git reset --hard HEAD) because git does not rewrite a
+# file whose blob is unchanged.
