feat: Enhance testing, CLI flag validation, and AI capabilities

This commit introduces several significant improvements:

- **Enhanced Unit Testing:**  Vastly improved unit tests for the  module, covering core functions, edge cases, and error handling.  Simplified test functions and comprehensive mocking were implemented for better isolation and reliability. Added new section to tests.mdc detailing reliable testing techniques.

- **CLI Kebab-Case Flag Enforcement:**  The CLI now enforces kebab-case for flags, providing helpful error messages when camelCase is used. This improves consistency and user experience.

- **AI Enhancements:**
    - Enabled 128k token output for Claude 3.7 Sonnet by adding the  header.
    - Added a new task to  to document this change and its testing strategy.
    - Added unit tests to verify the Anthropic client configuration.
    - Added  and  utility functions.

- **Improved Test Coverage:** Added tests for the new CLI flag validation logic.
