mfsk-core 0.7.4

Pure-Rust WSJT-family decoders + synthesisers (FT8 FT4 FST4 WSPR JT9 JT65 Q65) behind a zero-cost Protocol trait. Host (rustfft) or no_std embedded (ESP32-S3, RP2350, Cortex-M) via a pluggable FFT backend; fixed-point hot path for FPU-less MCUs. Ships with embedded-poc/m5stack-s3-app, a working M5StickS3 FT8 controller (LCD UI, BLE CI-V to IC-705, acoustic mic, QSO FSM) decoding real on-air signals in ~1.2 s post-SlotEnd on Xtensa LX7.

//! Re-export of the WSJT 77-bit message codec from `mfsk-msg`.
//!
//! The actual implementation lives in [`crate::msg::wsjt77`]. This façade exists
//! so existing `ft8-core::message::{pack77_*, unpack77, …}` callers keep
//! working during the migration. New code should import from `mfsk-msg`
//! directly.
