archy went deaf to inbound LoRa packets after every config write.
A config write (region/channel/owner) reboots the radio, which resets
the firmware PhoneAPI to STATE_SEND_NOTHING; it won't stream received
packets again until the client re-sends want_config. archy ignored
FromRadio.rebooted (field 8) so never resubscribed — which is why old
messages only arrived after a full restart (restart = fresh want_config).
- meshtastic.rs: handle FROM_RADIO_REBOOTED -> set pending_reinit;
try_recv_frame re-sends want_config to resubscribe the packet stream.
Add send_keepalive (bare heartbeat) and pin modem_preset=LONG_FAST in
set_lora_region so all radios share frequency.
- listener/session.rs: MeshRadioDevice::send_keepalive; 10s sync_timer
sends a keepalive each tick (insurance vs 15-min idle serial close).
- mod.rs send_message: device-aware send — Meshtastic archy peers get a
plain TEXT_MESSAGE_APP DM (firmware PKC E2E); Meshcore archy peers keep
the typed envelope (no meshcore regression).
Verified: .198->.228 directed DM arrives as RECEIVED enc=True
peer="Arch Optiplex"; all 3 nodes (.116/.198/.228) + 3ccc hear each
other. Binary 737b16c3 deployed+active on all three.
