Both e2e directions time out: nothing is delivered between nodes although
the adapter connects fine and bridging code is equivalent to meshtastic's own
firmware_harness. Before concluding, instrument the pinned meshtasticator:
- on_receive now prints every observed packet (topic keys) to sim.log,
- a [sim-text] listener prints any text packet any sim interface sees,
- cleanup sends 'exit' through the cmdloop (graceful, no EOF-spam flood that
was drowning the log tail),
- workflow failure step prints 400 sim-log lines + the node logs dump.
