tests/mesh/run-mesh-tests.sh: cheap-first layers — 116 Rust mesh unit
tests, the daemon --selftest (now also asserting the announce app_data
wire contract and the set_name verb), and opt-in live assertions against
a running node (radio connected, named, mesh.refresh/broadcast, no
ARCHY-blob peer names). Verified green on archi-dev-box and archy-x250-dev.
