Remove AI/Gemini integration and optimize dependencies

[Copilot]

Removed AI chat functionality and unused dependencies to reduce bundle size and deployment complexity.

Changes

Removed AI/Gemini Integration

• Deleted services/geminiService.ts and all chat UI components (side panel, floating button)
• Removed @google/genai dependency and related types (Message, GroundingSource)
• Cleaned up environment configuration and Vite defines

Optimized Dependencies

Eliminated unused packages, reducing dependency count from 197 to 68:

• @cloudinary/url-gen and @cloudinary/react → replaced with native fetch for uploads
• recharts → not used anywhere in codebase
• Removed unused importmap from index.html

Before:

import { Cloudinary } from '@cloudinary/url-gen';
export const cloudinary = new Cloudinary({ ... });

After:

export const uploadImage = async (file: File): Promise<string> => {
  const formData = new FormData();
  formData.append('file', file);
  const response = await fetch(`https://api.cloudinary.com/...`, {
    method: 'POST',
    body: formData
  });
  return response.json().secure_url;
};

Updated Documentation

Rewrote README to reflect simplified architecture and deployment process.

Impact

• Bundle: 12KB total
• Build time: ~76ms
• Dependencies: -65%
• Code: -122 lines in App.tsx

Preserved Functionality

• Admin panel with Cloudinary uploads
• WhatsApp B2B integration
• Product catalog and search
• Theme switching
• Responsive design

Original prompt

Optimize and clean up the Nexlyn website codebase and remove AI/Gemini functionality to make the site lighter. Perform a project-wide cleanup to remove unused/duplicate code and assets, ensuring the site builds and runs cleanly. Focus on:

• Remove AI/Gemini integrations and related UI/components.
• Simplify dependencies and configuration where possible.
• Ensure the site is lightweight and deployable (Vercel-friendly).
• Verify admin panel and other sections still function appropriately after cleanup.
• Update README if needed to reflect changes.
