Make Nx the primary build workflow for the desktop docs

Promotes npx nx serve desktop as the recommended build path, including
native module compilation via npx nx build-native desktop, and moves
the npm-script instructions to a Manual build commands section.

 ## Build native module
 
 The desktop application relies on a native module written in rust, which needs to be compiled

+npx nx serve desktop

+## Manual build commands

+Before the migration to Nx, the desktop application was built and run directly with npm scripts.
+These commands are still available but are no longer the recommended approach.
 
 ```bash
 cd apps/desktop
 npm run electron
 ```
 
+This script also compiles the native module before launching Electron.
