Pull request overview

Adds a new VoIP call React Native example under mobile-react-native/voip-call/, consisting of an Expo client app and a small Deno push + signaling server to demonstrate ringing via native call UI (CallKit/Telecom) and connecting via a Fishjam room.

Changes:

• Introduces an Expo React Native VoIP calling client with login, user list, call screens (audio/video), and call lifecycle hooks.
• Adds a Deno server providing user registration, push routing (APNs/FCM), WebSocket signaling relay, and avatar serving.
• Adds setup/run documentation plus per-project tooling/config (Deno tasks/lockfile, Expo config, ESLint/Prettier, env examples).
