Supabase Edge Function Timeouts or Fails to Execute

1. Long-running operations exceeding 120 second timeout
2. Waiting for external API without timeout
3. Database query returning too much data
4. Missing await on async operations
5. Cold start delays on first invocation

Add timeout to external requests:

const controller = new AbortController();
const timeoutId = setTimeout(() => controller.abort(), 5000);

const response = await fetch(url, { signal: controller.signal });
clearTimeout(timeoutId);

Offload long operations to background jobs. Optimize database queries with indexes and limits.
