Improve CI/CD Caching Documentation and User Guides

Issue Description

Title: Create Comprehensive Documentation for Multi-Project Caching Implementation
Priority: High
Type: Documentation / User Experience

Overview

Following the implementation of multi-project caching strategies (Issue #2 (closed)), we need comprehensive documentation to help development teams understand, implement, and troubleshoot caching in their projects.
Currently, there is limited guidance for developers on how to use the new caching framework effectively.
