- Add ping-on-connect handshake: all connect functions validate the device within 200ms, rejecting non-DongLoRa serial devices immediately - Add try_connect() — non-blocking connect that errors instead of blocking forever when no USB device is present - Add payload size validation in transmit() (max 256 bytes) - Add ErrorCode: impl std::error::Error - Fix drain_rx error handling (no longer swallows original error) - Fix repository URL to github.com/donglora/client-rs - Remove wire-level tag constants from top-level re-exports - Add rust-version (MSRV 1.85), homepage, exclude fields to Cargo.toml - Add examples/ping.rs - Allow clippy unwrap/expect in test modules
