refactor(fs): Use structuredClone for Resource statInfo deep copy

The `clone` package recreates internal-slot-backed values like Date and
Temporal.Instant as prototype-only copies, stripping the slot. On Node 26
fs.Stats exposes Temporal.Instant getters whose toJSON performs a strict
internal-slot check and throws, breaking any consumer that JSON-stringifies
a cloned stat (e.g. @ui5/builder's theme worker IPC).

Replace `clone` with a small helper that preserves the prototype, copies
function-valued own properties by reference, and runs each data value through
structuredClone — which correctly handles Date, Temporal, Map, Set, typed
arrays, etc. sourceMetadata uses structuredClone directly. The unmaintained
`clone` dependency is removed from @ui5/fs.

This is an up-port of https://github.com/SAP/ui5-fs/pull/697 hence the
commit message is not using the "fix" prefix.
