📝 Walkthrough

Walkthrough

This PR refactors the hints router setup by moving the dev-server handler registration logic into a dedicated function. The createHintsRouter function is made private and reconfigured to use preemptive: true. A new exported registerDevServerHandlers() function encapsulates router creation and registration with Nuxt Dev Server at the /__nuxt_hints route. The integration point in devtools.ts is updated to call this function instead of managing registration inline.
