Fix AI SDK package resolution in Vercel deployment

Resolves the "Cannot find package '@ai-sdk/gateway'" error by:

1. Added @ai-sdk/* packages as optional peer dependencies in service-ai
   - These are only needed when specific env vars are set
   - Marked as optional to avoid installation errors when not needed

2. Added @ai-sdk/* packages as dependencies in studio app
   - Required for LLM auto-detection feature in production

3. Updated esbuild external list to exclude @ai-sdk packages
   - Prevents bundling so dynamic imports work correctly
   - Allows runtime resolution from node_modules

4. Updated build-vercel.sh to copy @ai-sdk packages
   - Copies packages from monorepo to local node_modules
   - Required for Vercel's pnpm workspace resolution

5. Updated vercel.json includeFiles to bundle @ai-sdk packages
   - Ensures packages are included in serverless function

This allows the AI service to gracefully detect and load LLM providers
based on environment variables without build-time bundling issues.
