Move E2B sandbox outputs to project root with organized folders

Changes:
- E2B outputs now save to ./e2b-outputs/{timestamp}_{prompt}/ in project root
- No longer creates files inside .claude directory
- Added timestamp and sanitized prompt name for unique folder organization
- Improved find command to exclude .claude and node_modules directories
- Enhanced file filtering and organization for better user experience

Structure:
./e2b-outputs/
  └── 20250106_143025_Create-React-app/
      ├── index.html
      ├── app.js
      └── styles.css

This keeps E2B sandbox outputs separate from Claude Code configuration
and makes it easier for users to find and manage their generated files.
