Refactor UI design workflow scripts and documentation

- Removed the generation of a unified consolidation report in the consolidate.md file, streamlining the output structure.
- Updated the extract.md file to prioritize the --base-path argument for session management and improved error handling for style variant detection.
- Enhanced generate.md to enforce critical requirements for layout templates, ensuring independence from other targets.
- Added a comprehensive analysis report for the ui-instantiate-prototypes.sh script, detailing issues with style variant mismatches and proposing solutions for validation and prevention.

+          - Do NOT include content from other targets in the workflow
+          - This template is for '{target}' ONLY - treat it as a standalone UI entity

           Generate a **style-agnostic** layout template for a specific {target_type} and layout strategy, informed by modern web development best practices.
 
           🎯 **CRITICAL REQUIREMENTS**:
           ✅ **ADAPTIVE**: Multi-device responsive design (mobile, tablet, desktop)

           ✅ **TOKEN-DRIVEN**: 100% CSS variable usage, zero hardcoded values
+          ✅ **INDEPENDENT**: Template for '{target}' only, no other targets included
