Introduce ActionValidationStatus enum (valid, unresolved, missing_argument, invalid_argument, ambiguous_target) as the typed classification of validation outcomes. ActionValidationResult now carries Status instead of boolean flags. Backward-compatible: Unresolved() and Valid() methods preserved on the result. Existing validation behavior unchanged: only blank Fn produces invalid_argument. All downstream behavior (proposeGap, confirmation, task_status, praxis, hexis) unchanged. Tests added for all five status values, backward compatibility, and the full validation → execution boundary.
