feat: reorganize codebase with single source of truth + merge prompts into styles

BREAKING CHANGES:
- Moved canonical data/scripts to src/ui-ux-pro-max/
- Removed duplicate folders (.codex/, .gemini/, .trae/, .codebuddy/, .continue/, skills/, .qoder/)
- CLI now uses template system instead of copying pre-built folders

New features:
- Merged prompts.csv into styles.csv with 4 new columns:
  - AI Prompt Keywords
  - CSS/Technical Keywords
  - Implementation Checklist
  - Design System Variables
- All 67 styles now have complete prompt data
- Added Astro stack (53 guidelines)
- Added 10 new 2025 UI trend styles

CLI changes:
- New template rendering system (cli/src/utils/template.ts)
- Reduced cli/assets from ~34MB to ~564KB
- Assets now contain only: data/, scripts/, templates/

File structure:
- src/ui-ux-pro-max/ - Single source of truth
- .claude/skills/ - Symlinks to src/ for development
- .shared/ - Symlink to src/ui-ux-pro-max/

Bumped CLI version: 2.1.3 → 2.2.0
