- 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).

I think i may have done this PR wrong, it's trying to merge into main instead of dev i think |

I have been testing a longer preamble (32) instead of (16) i have had major tx reliability improvements for strong and weak links. This wasn't a noticeable issue on wide (250khz, sf11) But narrow seems to have this issue. My theory is that narrow's higher spectral density and the lower noise floor is causing the AGC to have to make a larger jump and the preamble is not long enough for the AGC to settle and the lora chip to reliably sync the packet clock and freq.
