Returns a JavaScript snippet that should be prepended to a Runtime
action's user code. It installs the utilities object whose methods
route through __bridgeCall to the host-side handlers defined in this
file.
Keeping this as a string (rather than a file) keeps it colocated with the
handler definitions so any change to the surface here naturally updates
the sandbox surface too. Do not add logic to this snippet beyond what is
strictly required to forward calls — all security / permissions live
host-side.
