//! DongLoRa host library — connect, configure, send/receive LoRa packets.
//!
//! Implements the DongLoRa Protocol v2 on top of the
//! [`donglora-protocol`](donglora_protocol) wire crate. All I/O is
//! async via tokio; the public surface mirrors the Python client in
//! `client-py/`.
//!
//! # Quick start
//!
//! ```no_run
//! # async fn demo() -> Result<(), donglora_client::ClientError> {
//! use donglora_client::{
//!     connect, LoRaBandwidth, LoRaCodingRate, LoRaConfig, LoRaHeaderMode, Modulation,
//! };
//!
//! let dongle = connect().await?;
//! dongle.set_config(Modulation::LoRa(LoRaConfig {
//!     freq_hz: 910_525_000,
//!     sf: 7,
//!     bw: LoRaBandwidth::Khz62,
//!     cr: LoRaCodingRate::Cr4_5,
//!     preamble_len: 16,
//!     sync_word: 0x1424,
//!     tx_power_dbm: 20,
//!     header_mode: LoRaHeaderMode::Explicit,
//!     payload_crc: true,
//!     iq_invert: false,
//! })).await?;
//! dongle.tx(b"hello world").await?;
//! # Ok(()) }
//! ```
//!
//! # Module layout
//!
//! - [`connect`] — auto-discovery + [`ConnectOptions`] builder.
//! - [`dongle`] — public [`Dongle`] radio session type.
//! - [`session`] — internal async plumbing (not public).
//! - [`transport`] — tokio-based byte-stream transports.
//! - [`errors`] — [`ClientError`] taxonomy.
//! - [`retry`] — [`RetryPolicy`] + [`TxOutcome`] for `tx_with_retry`.
//! - [`discovery`] — USB VID/PID scan + async `wait_for_device`.
