Refactored handoff-ready codebase

Seatu is now structured as a modular AI commerce platform.

Build one shared commerce engine, then surface it through web chat, WhatsApp, Instagram, seller tools, and future automation.

What this refactor changes
  • • product search and recommendation logic moved into dedicated AI modules
  • • conversations and memory stored in Supabase
  • • UI split into small components instead of very long files
  • • channel adapters added for WhatsApp and Instagram
  • • multilingual support surfaced in the storefront
