shared/utils/typeGuards

Comprehensive type guard utilities for enhanced type safety.

Remarks

This module provides centralized type checking logic using proper TypeScript type predicates. Each utility function is a type guard that narrows the type of the checked value. All TSDoc tags follow the official TSDoc standard.
