hack: unquoted ${REPO_ROOT_DIR} inside mktemp call in verify-codegen.sh

[Ankitsinghsisodya]

Problem

hack/verify-codegen.sh line 25:

readonly TMP_DIFFROOT="$(mktemp -d ${REPO_ROOT_DIR}/tmpdiffroot.XXXXXX)"

${REPO_ROOT_DIR} is unquoted inside the mktemp argument. If the repository root path contains spaces, the shell splits the argument and mktemp receives the wrong input, causing it to fail or create a temp directory in the wrong location.

Proposed Fix

readonly TMP_DIFFROOT="$(mktemp -d "${REPO_ROOT_DIR}/tmpdiffroot.XXXXXX")"
