* NodeDB: encode satellite maps in place when saving
saveNodeDatabaseToDisk() copied each satellite map into nodeDatabase's
vectors just to encode them, so every save needed a second, contiguous
copy: up to ~19 KB at the nRF52 cap of 40, 40 x 312 B for environment
alone. On busy meshes this ran nRF52 sensor nodes out of heap
(new(10920) failed in saveNodeDatabaseToDisk()).
Mirror the decode path: arm per-map encode sources for the duration of
the save, and have the NodeDatabase encode callback walk the map, one
stack entry at a time. Same entries in the same order, so nodes.proto
is byte-identical.

* NodeDB: clear satellite vectors before encoding the save
With a satellite DB compiled out, nodes.proto's entries for it still
decode into nodeDatabase's vector. The projection used to clear those
vectors before encoding; without that, the first save after boot wrote
the stale entries back. Clear all four before arming the encode sources;
an armed source ignores its vector anyway.

Meshtastic Firmware
Overview
This repository contains the official device firmware for Meshtastic, an open-source LoRa mesh networking project designed for long-range, low-power communication without relying on internet or cellular infrastructure. The firmware supports various hardware platforms, including ESP32, nRF52, RP2040/RP2350, and Linux-based devices.
Meshtastic enables text messaging, location sharing, and telemetry over a decentralized mesh network, making it ideal for outdoor adventures, emergency preparedness, and remote operations.
