Update project structure and documentation: Add new entries to .gitignore for standalone outputs and MCP config, delete obsolete design_skill.md file, and revise README and various skills to reflect updated workflow steps, including UI design and performance testing. Adjust paths in retrospective and metrics documentation to align with new directory structure.
