//! # `chanora_bridge`
//!
//! Typed Flutter/Rust bridge — schema-controlled DTOs for commands,
//! results, and events. Backed by `flutter_rust_bridge` 2.x per
//! DEC-014.
//!
//! ## Alpha scope
//!
//! Exposes three commands that target the Alpha release goal:
//!
//! * `bridge_init()` — one-time process initialisation. Sets up
//! logging.
//! * `connect(host, nickname)` — connects to a TS3-compatible
//! server and returns a typed [`ConnectResultDto`] containing the
//! server snapshot.
//! * `disconnect()` — clean disconnect.
//! * `snapshot()` — re-fetch the current server snapshot.
//!
//! No audio commands cross the bridge in Alpha; audio is Beta scope.
//!
//! ## Boundary discipline
//!
//! Every type in this module is `Serialize + Deserialize` over owned
//! primitives or `String`s. No `tsclientlib`, `cpal`, or backend
//! types may appear in the public surface (SAD-067, SDD-079).
//!
//! Note: this crate cannot use `#![forbid(unsafe_code)]` because the
//! FRB-generated glue (in `frb_generated`) legitimately uses unsafe
//! for the FFI boundary. Hand-written code in this crate must
//! nonetheless avoid `unsafe` and is held to that standard by review.
