Rewrite the README to reflect the current project: dual-transport
(Meshtastic base + MeshCore auto-on via meshcore_host), the web dashboard
(with live screenshots), per-mesh routing, the conversational bot with
per-mesh scoped context + three privacy lanes, environmental/hazard
broadcasts, mesh-health scoring, and the RAG knowledge base. Removes the
retired subscription backend/commands, updates the LLM model + architecture,
and adds live dashboard screenshots under docs/images/.
For transparency, documents that the project was vibecoded (built with LLM
coding assistants).
