feat: sync web-preview with actual NPM module

- Replace duplicate core logic in web-preview with actual module import
- Add local file dependency (@253eosam/commit-from-branch: file:..)
- Export required types from main module for web-preview compatibility
- Update GitHub Pages workflow to build root module first
- Remove duplicate tokens.ts file from web-preview
- Ensure perfect feature synchronization between module and demo

This ensures the demo always reflects the actual published module behavior.
