Adds an "AI" item to the sidebar nav (mirrors Vibespace's /ai route,
already wired in routes.ts). vite.config.ts now lists openapi-fetch,
phoenix, lucide-react, clsx, tailwind-merge, class-variance-authority
in optimizeDeps.include and adds explicit resolve.alias entries for
the arcadia and crema sibling libs so Vite resolves them on first
load instead of triggering a re-optimize mid-session.
