fix: improve testing and CLI command implementation

Browse Source 
- Fix tests using ES Module best practices instead of complex mocking
  - Replace Commander.js mocking with direct action handler testing
  - Resolve ES Module import/mock issues and function redeclaration errors
  - Fix circular reference issues with console.log spies
  - Properly setup mock functions with jest.fn() for method access

- Improve parse-prd command functionality
  - Add default PRD path support (scripts/prd.txt) so you can just run `task-master parse-prd` and it will use the default PRD if it exists.
  - Improve error handling and user feedback
  - Enhance help text with more detailed information

- Fix detectCamelCaseFlags implementation in utils.js yet again with more tests this time
  - Improve regex pattern to correctly detect camelCase flags
  - Skip flags already in kebab-case format
  - Enhance tests with proper test-specific implementations

- Document testing best practices
  - Add comprehensive "Common Testing Pitfalls and Solutions" section to tests.mdc
  - Provide clear examples of correct testing patterns for ES modules
  - Document techniques for test isolation and mock organization
