New m5_echo/ firmware for the ATOM Echo (ESP32-PICO-D4) with push-to-talk: - Auto-starts call on boot via PTT multicast announcement - Button hold = record mic (PDM, mu-law), release = listen - Persistent TCP connection survives PTT cycles (Opus task discards frames during PTT instead of closing connection) - Handles ESP32 I2S ALL_RIGHT stereo quirks (2x sample rate compensation for both mic and speaker) - Includes flash script, serial terminal, and integration test tools Also adds PTT_MODE flag to onjuino for bridge compatibility (multicast announcement, auto-start call, skip VAD mic timeouts).
