supportsTakV2
Support for the v2 TAK port (ATAK_PLUGIN_V2 = 78) with TAKPacketV2 + zstd dictionary compression. Supported since firmware v2.8.0. Firmware v2.7.x and earlier only support the legacy ATAK_PLUGIN port (72) with the original TAKPacket schema (PLI + GeoChat only, no compression), so the bridge falls back to that path for older nodes.
