feat(update.sh): vendor gum binary for the R9700's offline install

The server has no outbound internet access, so the curl download in
ensure_gum always failed silently and fell back to plain prompts.
Vendor the x86_64 release tarball under scripts/vendor/ and check it
before attempting a download - download stays as a fallback for other
archs or a version bump without a re-vendor.
