Šepot — end-to-end encrypted messenger

Initial public release. Anonymous on-device identity (no phone number, e-mail, or password), Signal-protocol cryptography (X3DH + PQXDH, Double Ratchet, sealed sender) via libsignal, a metadata-minimizing relay, group chats, disappearing messages, encrypted local storage, optional Tor transport, and a UI localized into Czech, English, German, Russian, and Italian. Monorepo: Flutter client (app/), Rust relay + wire types (rust/), protobuf definitions (proto/), self-host deploy (deploy/). Licensed under AGPL-3.0 with an app-store distribution exception (§7).

+/// Přepínač routování přes Tor (SOCKS5/Orbot na `.onion`).
+///
+/// Zapnutí skryje IP klienta před relayem — provoz jde přes lokální
+/// Orbot. Bez běžícího Orbotu se spojení nenaváže (indikátor zůstane
+/// „připojuji"), na což uživatele upozorníme předem. Přepnutí přestaví
+/// spojení za běhu, restart appky netřeba.
