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).

+/// Numerická klávesnice pro PIN + řádek teček.
+///
+/// Vytaženo z `pin_setup_screen`, aby ji mohla použít i změna PINu.
+/// Systémovou klávesnici záměrně nepoužíváme — nechceme, aby PIN prošel
+/// IME (predikce, schránka, klávesnice třetích stran).
