Overview

Bundles a directory tree into a single ZIP archive on disk.
Optionally deletes the source directory after writing
(cleanup: true) so callers can stage temporary export bundles
without manually unwinding them. Used by exports such as the
DesignToolFixture CSV pack and the catalog-item asset packet.
