Meshtastic develop fork for Hydra boards (2.8.3-hdev)

Overview

Fork of the Meshtastic firmware develop branch, built for Hydra boards: ESP32 with a LoRa E22P-868M30S radio. Two hardware variants come from this tree:

• hydraE22P - ESP32 without PSRAM.
• hydraE22P_psram - Freenove ESP32-WROVER board with PSRAM (up to 1000 nodes).

Main additions over upstream: node statistics on demand (OnDemand), telemetry and position limiters, opportunistic flooding, NodeMod / SignalReply, Wi-Fi and Bluetooth TX power settings, and extra diagnostics (channel utilization, flash and heap counters, relay and duplicate counters). Based on upstream develop from 2026-11-02.
