Implements a typed mesh snapshot API in `@fusion/core` (`CentralCore.getMeshSnapshot`, `MeshSnapshot` type) and wires it through the dashboard nodes view via a new `useMeshState` hook, substantially simplifying `MeshTopology.tsx` by replacing internal state management with the centralized snapshot.

Merges node discovery onboarding (FN-3506) with two steps: a pre-registration discovery contract wired into the AddNodeModal UI, and full remote discovery integration with documentation. Also adds a local embedded runtime manager to the desktop app (FN-3404) and wires permanent-agent approval contex

This merge introduces three major features: a full path-mapping API layer across core, dashboard, and desktop (FN-3504, four commits), shell multi-profile support with a new NativeShellConnectionManager component and connection manager onboarding flow (FN-3403), and migration of the WhatsApp plugin
