fix: remove warnings from useDeepCompareEffect

Removes the console warnings that were showing up in dev. The hook works
fine with primitives, objects, or undefined - the warnings were just
annoying for valid use cases.

Fixes #755

+## When to Use
+
+This hook is handy when:
+- Your dependencies might be `undefined` or an object (common with optional props/config)
+- You need to compare objects by their values, not just references
+- You're mixing primitives and objects in your dependency array
+
+Works fine with any dependency types - primitives, objects, or a mix of both.
