Fix PickOnlyUnexpectedKeysDoesCorrectlyError

✅ Solution

This error usually arises when the `pick` method on Zod objects doesn't properly enforce key constraints at compile time, allowing unexpected keys to slip through. To fix it, ensure the `pick` method's return type accurately reflects the picked schema and introduce a type-level check that explicitly verifies the provided keys in the `pick` call are valid for the original Zod object schema, throwing a TypeScript error otherwise. This will re-establish compile-time safety.
