# Implement UUID Generation Function

## Task
Write a function to generate a UUID (Universally Unique Identifier).

## Acceptance Criteria
All tests must pass.

## Summary of Changes
Added a new utility function to generate Universally Unique Identifiers (UUIDs) using a cryptographically secure random number generator. The implementation ensures unique identifier creation for various system use cases.

## Test Cases
 - Verify the generated UUID is a valid 36-character string
 - Confirm the generated UUID follows RFC 4122 version 4 format
 - Ensure two consecutive UUID generations produce different values
 - Check that the UUID contains correct hyphen placement
 - Validate the UUID contains only hexadecimal characters and hyphens
