IValidationHook defines the structure for custom validation functions
that can be provided for each method in the application class. It creates a
mapped type where each property corresponds to a method in the class, and
the value is a validation function for that method's parameters.
The validation hook functions:
Receive the same argument type as the original method
Must return an IValidation result indicating success or failure
Replace the default type validation when specified
Enable custom business logic and runtime validation
Type constraints:
Only methods (functions) from the class can have validation hooks
Non-function properties are typed as never and cannot be validated
The validation function must match the method's parameter signature
Type Parameters
