Run this script once to create the Supabase users table.
Usage: python scripts/migrate_supabase.py

Requires the SUPABASE_URL and SUPABASE_SERVICE_KEY env vars to be set.
This uses the Supabase REST API to execute SQL via the pg_query extension.
If that fails, manually run migrations/001_create_users.sql in your Supabase SQL editor.
