Adds a skip-gated end-to-end suite (plugin/tests/e2e) that drives the
adapter against live Meshtasticator simulated nodes - real MeshtasticD
instances speaking the actual TCP/protobuf API - covering the layer no
contract test can reach: TCP handshake, inbound text over the simulated
mesh, and chunked outbound sends arriving at a peer node.
scripts/meshtasticator_e2e/run_e2e.sh boots N nodes (Docker or Linux
native MeshtasticD), discovers their TCP API ports, and runs the suite.
Radio-level reconnect and CI wiring are documented as open items pending
a Linux/Docker validation run.
