feat: Implement dynamic test-fix execution phase with adaptive task generation

- Added Phase 2: Test-Cycle Execution documentation outlining the process for dynamic test-fix execution, including agent roles, core responsibilities, intelligent strategy engine, and progressive testing.
- Introduced new PowerShell scripts for analyzing TypeScript errors, focusing on error categorization and reporting.
- Created end-to-end tests for the Help Page, ensuring content visibility, documentation navigation, internationalization support, and accessibility compliance.
