Introduction of Context Class for Plugin Architecture

[rafaelherik]

Overview

Implement a Context class to establish a foundation for future plugin capabilities in the Terraform plan analyzer. This architectural change improves the system's extensibility and provides a centralized way to manage configuration, logging, and shared state.

Technical Details

The Context class serves as a dependency injection container and configuration manager, providing:

1. Centralized Configuration Management

   • Handles loading and merging of default and custom rule configurations
   • Manages sensitive pattern definitions and risk rules
   • Provides a unified interface for configuration access

2. Logging Infrastructure

   • Configurable logging levels (DEBUG/INFO)
   • Consistent logging format across the application
   • Centralized logging configuration

3. Plugin Architecture Foundation

   • Acts as a shared state container between components
   • Provides a standardized interface for future plugin interactions
   • Enables dependency injection for better testability

Implementation Benefits

• Loose Coupling: Components can now communicate through the context rather than direct dependencies
• Improved Testability: Easier to mock dependencies and configurations in tests
• Configuration Flexibility: Supports both default and custom configurations with clean merge logic
• Future Extensibility: Provides a clean interface for plugin developers to access and extend functionality
