[v25.x] lib: do not provide an empty Proxy from localStorage getter
Addresses the original regression in a way that is more consistent with the user experience in v24.x where no storage-related CLI arguments are passed. Access now warns and returns undefined in the case where the requisite path is missing.
As things stand, the behaviour will revert to exception-raising in v26.x; any discussion relating to this specifically should go in the associated issue, this PR is just to re-fix the regression for localStorage users in v25.
