fix(windows): keep shebang scripts LF on checkout

The previous .gitattributes only pinned *.sh/*.bash to LF. With
core.autocrlf=true a Windows clone still checked out bin/cli.js and
scripts/*.mjs with CRLF, so the '#!/usr/bin/env node' line kept a
trailing \r: Vite's shebang strip missed it and importing
scripts/restart.mjs from a test failed with 'Invalid or unexpected
token'. Pin *.js/*.mjs/*.cjs/*.py to LF too.
