- Trigger noise floor calibration every 2s and AGC reset every 30s in main loop.
- Reorder loop to match Dispatcher: calibrate + radio.loop() before AGC reset
and recvRaw() so RSSI is never sampled right after startReceive().
- Update protocol doc with calibration intervals and typical noise floor range.
- Variant platformio.ini updates (heltec_v3, rak4631).
- Introduced new commands for retrieving statistics: CMD_GET_STATS_CORE, CMD_GET_STATS_RADIO, and CMD_GET_STATS_PACKETS.
- Implemented corresponding response handling methods to format and send statistics data.
- Updated MyMesh constructor to initialize new member variables for managing statistics.
- Included StatsFormatHelper for formatting statistics replies.
