Supabase Realtime API

The Supabase Realtime API provides WebSocket-based subscriptions for real-time data changes from PostgreSQL databases. It supports three channel types: database change events (INSERT/UPDATE/DELETE on tables via logical replication), presence (track and synchronize connected users' state), and broadcast (low-latency message passing between clients). Authentication uses JWT tokens. Implemented using the Phoenix channels protocol.
