proto addition from kamiden

[Cooops]

corresponding PR in kamiden, but tldr:

1. Clients can now subscribe to specific event types (KILL, KAMI_CAST, MOVE, etc.) instead of receiving everything
2. ~40-50% bandwidth reduction for clients that filter
3. 100% backwards compatible (empty topics = all events, like before)

Summary by CodeRabbit

• New Features
  • Added support for filtering stream events by topics. Users can now specify which topics to subscribe to, with backwards compatibility—omitting topics will stream all events.

Poem

🐰 Hop, skip, and topics we go,
Streams now filter, high and low,
Empty arrays, sorted neat,
Proto fields make code complete! 🌱
