Key features: - Binary payload support for user messages - Two new message types: user broadcast and user broadcast push - Optional metadata support for user broadcast push messages - Reduced JSON encoding overhead on the server side - Backward compatible with V1 (1.0.0) as default Changes: - Added RealtimeBinaryEncoder and RealtimeBinaryDecoder classes - Added RealtimeSerializer protocol for future extensibility - Updated RealtimeClientOptions to support serializer version selection - Updated RealtimeClientV2 to use binary serializer when v2.0.0 is selected - Added RealtimeBinaryPayload helper for working with binary data - Comprehensive test suite with 16 tests covering encoding/decoding scenarios References: - supabase/supabase-js#1829 - supabase/supabase-js#1894 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
