Multiplayer sync with custom people menu

Build a custom people menu that lists connected collaborators and their cursor positions.

---

Replace the SharePanel slot with your own component and read editor.getCollaborators() inside useValue. Each entry is a TLInstancePresence record with the collaborator's name, color, cursor, camera, and selection, so you can render a richer or differently styled presence indicator than the default facepile.

Open the example in two tabs to see the other user appear in the list.
