Replace the recommended Android client in README.md and README.en.md: swap vk-turn-proxy-android for wireguard-turn-android and update the link and brief description (it's a modified WireGuard client with built-in TURN). Remove the previous explicit WireGuard config/exception steps from the recommended method while leaving the Termux alternative unchanged.
Introduce multi-user proxy sessions: add an English README and update the Russian README. Server: implement SessionManager and UserSession to aggregate DTLS streams by a 16-byte session ID, create a single UDP backend per session, and deliver backend->client traffic using round-robin across active DTLS streams. Simplify per-connection logic (read session ID after DTLS handshake, reuse backend, improved accept/handshake/error handling). Client: add -session-id flag, generate or parse a 16-byte UUID, send the session ID immediately after establishing each DTLS stream, and propagate sessionID through connection loops. These changes improve stability (prevent endpoint thrashing) and enable multiple simultaneous users per proxy server.
