Ryan Malloy 6dffd936ae feat: add Heltec V3 LoRa TX beacon firmware
PlatformIO project for ESP32-S3 + SX1262 (Heltec WiFi LoRa 32 V3).
Transmits periodic LoRa packets matching gr-lora_sdr receiver params:
SF7, BW125kHz, CR4/5, 915MHz, sync word 0x12, CRC enabled.

Verified end-to-end: beacon TX → RTL-SDR → Docker gr-lora_sdr → decoded
"GR-MCP #N" payloads with valid CRC.

This directory is intended for PlatformIO Test Runner and project tests.
Unit Testing is a software testing method by which individual units of
source code, sets of one or more MCU program modules together with associated
control data, usage procedures, and operating procedures, are tested to
determine whether they are fit for use. Unit testing finds problems early
in the development cycle.
