Subject: [PATCH] fix(monaco): cross-platform postinstall via Node script

Replace Unix-only shell one-liner (mkdir -p / printf / cp -r) with a
Node.js ESM script (scripts/copy-monaco.mjs) that works on Windows,
macOS and Linux alike. The script still writes public/monaco/.gitignore
to keep copied assets out of git.
