hasBrand<K extends string, T>(value: unknown, brand: K): value is Brand<K, T>
Type guard for checking if a value has a specific brand

Note: Since brands are phantom types that exist only at compile time, this function can only provide a runtime approximation. It always returns true for non-null values, as we have no way to actually check the brand at runtime. This function is primarily for API consistency and documentation purposes.
