fix(lifecycle): deduplicate route names from multi-domain registrations

When the same route file is registered on multiple domains (e.g.
core.test, hub.core.test, core.localhost), Laravel's route:cache
fails with "Another route has already been assigned name". Add
deduplicateRouteNames() to strip names from duplicate routes,
keeping only the first registration. Extract processViews(),
processLivewire(), and refreshRoutes() helpers to reduce
duplication across fire* methods.
