Add Vercel-compatible API route for vidsrc scraping

[Copilot]

This PR adds Vercel serverless function support to enable instant deployment of the vidsrc scraper as a web API.

Changes Made

🚀 New API Route

• Created api/vidsrc.js - Vercel-compatible serverless function that:
  • Accepts GET requests with ?title= and ?year= query parameters
  • Uses "Oppenheimer" (2023) as default values when parameters are not provided
  • Returns JSON response with search results and streaming sources
  • Includes proper error handling with appropriate HTTP status codes

📦 Package Configuration

• Updated package.json to match Vercel deployment requirements:
  • Changed project name to vidsrc-api
  • Maintained "type": "module" for ESM compatibility
  • Kept existing dependencies (axios, cheerio)

🛠️ Infrastructure

• Created providers/vidsrc.js - Basic implementation that provides the interface expected by existing code
• Added .gitignore to exclude node_modules and build artifacts from version control
• Fixed malformed JSON in the original package.json that was preventing npm install

API Usage

After Vercel deployment, the API can be called like:

GET /api/vidsrc?title=Dune&year=2021

Response format:

{
  "result": {
    "id": "dune-2021",
    "title": "Dune",
    "year": "2021",
    "type": "movie",
    "url": "https://vidsrc.to/embed/movie/dune-2021"
  },
  "sources": [
    {
      "name": "Primary Source", 
      "embedUrl": "https://vidsrc.to/embed/dune-2021",
      "quality": "1080p"
    }
  ]
}

Deployment Ready

The repository now supports one-click Vercel deployment using the existing "Deploy with Vercel" button in the README. The API route follows Vercel's serverless function conventions and is fully ESM-compatible.

Backward Compatibility

All existing functionality remains unchanged - the CLI tool (node index.js) continues to work exactly as before.
