For live co-GM play, the AI's narration now reaches the players' screens, and its
roll buttons already broadcast their results to the table (via rollAndShow →
broadcastGmRoll).
- When hosting a session (role gm + connected) and "Share narration with players"
is on, each director narration is pushed over the table chat channel (sendChat)
so players see the AI DM speak in their session feed. A no-op when not hosting.
- SceneControls gains the share toggle (default on); directorStore persists it.
Reuses the existing, e2e-tested realtime chat primitive — strictly additive, no
protocol/server change. GM stays authoritative. 395 tests green; lint clean;
build OK; page + controls verified rendering on a clean load.
