refactor: Add T constraint to useLocalStorage (#34)

* refactor: Add T constraint to useLocalStorage

The generic type `T` used in `useLocalStorage` is now constrained
to ensure it is a `Record<string, unknown>` or `undefined`. This
improves type safety and clarity.

* test: Adapt tests to use TestBlob structure

The tests for `useLocalStorage` were updated to correctly serialize and
deserialize values using the expected `TestBlob` structure (e.g.,
`{ testValue: "value" }`) when mocking initial data in
`localStorage`.

This ensures the tests accurately reflect how the hook handles data
wrapping/unwrapping in its generic usage context.
