feat(mesh): archy nodes run as RNS transport nodes

Browse Source 
The Reticulum daemon gains --enable-transport, which writes
enable_transport = yes into the RNS config it regenerates on every
start, and the Rust supervisor always passes it. Archy nodes now relay
RNS traffic and rebroadcast announces, so archy nodes (and Sideband/
NomadNet peers) beyond direct RF range discover and reach each other
through any archy node in between — edge-only operation left every
node limited to its own radio horizon. RNS's per-interface airtime
caps bound the extra announce overhead on LoRa.

Verified: config generation with the flag on/off, daemon --selftest
green with transport enabled, mesh test module 116/116.
