Fix Cloudflare Worker compatibility for version endpoint

- Add version parameter to AppConfig interface
- Pass version from environment config instead of using process.env
- Update worker.ts to pass VERSION environment variable
- Update wrangler.toml with VERSION variable
- Update deploy script to automatically set VERSION to git commit hash

This fixes the 'process is not defined' error in Cloudflare Workers
