fix: make the two new scripts executable

Both carry a shebang, and every other script in the directory is 755. Ruff's
EXE001 caught it in CI; the local run had a cached result from before the
files were written, so it passed here and failed there.

Worth noting for the next time a local check disagrees with CI: ruff's cache
key is the file content, and the executable bit is not part of it.
