• Polish installer startup so npm and Node.js setup stays behind the Prime splash with rotating progress detail.
• Read Prime Inference credentials from the Prime CLI config so prime login makes Prime Inference models available on startup.
• Skip a saved default model at startup when it no longer has configured auth, avoiding stale unauthenticated selections.
• Bootstrap the fd and rg search helpers from postinstall when opted in, and download them quietly so they no longer print over onboarding.
