fix(prog-shell): only auto-chmod scripts in prog-mode buffers

cj/make-script-executable runs from a global after-save-hook and set +x on any saved file whose first line was a shebang, in every buffer. A downloaded script you were reading, a template, or a shebang in a text or org file silently became executable. I gated it on derived-mode-p prog-mode, so it only acts on actual script buffers. Real scripts (sh-mode, python-mode) still get the fast path.
