Schedule Linux self announcements and retain full MeshCore discover keys.
Align adapter and worker PKI readiness, converge node metadata with public-key
identities, and preserve projected node IDs across persistence and restart.
Avoid routing-prefix self collisions and use local receive time for Nearby
freshness on embedded MC paths. Start MT NodeInfo reply suppression only after
successful transmission.
Add paired-radio discovery/direct-message, directory migration and worker
regressions with English audit and validation notes.
