Release v0.9.79 runtime and messaging update

Ship the v0.9.79 runtime refresh with transport lane isolation, Infonet secure-message address management, MeshChat MQTT controls, selected asset trail behavior, telemetry panel refinements, onboarding updates, and desktop/package metadata alignment.

Also ignore local graphify work products so analysis folders do not leak into future commits.
