hailin 549b21f298 fix(message-router): prevent subscription race condition on gRPC reconnect ... When a party re-subscribes (e.g., Android reconnects), the old gRPC stream's defer Unsubscribe() was accidentally removing the NEW subscription from the subscribers map, causing the party to miss session_started events. Fix: - Subscribe() now returns the channel to the caller - Unsubscribe() now takes the channel and only removes if it matches - This prevents older streams from removing newer subscriptions 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>		2026-01-01 10:04:11 -08:00
