Describe the Bug

When calling methods from a Map or Set object saved in a collection entry (for example via zod transforms), the following error occurs:

method called on incompatible Object

Calling methods on a Date object works.

I initially thought it could be related to devalue serialization but this test code doesn't crash

import * as devalue from 'devalue'
const from = new Set(['value']);
const store = devalue.stringify(from);
const to = devalue.parse(store)
console.log(from, store, to)
to.has('value')

What's the expected result?

Calling methods on Set or Map objects should work just like Dates.
