Module onboarding 

Interactive first-run setup wizard.

Inspired by @clack/prompts (OpenClaw, Vercel CLI, SvelteKit):

• intro() / outro() bookends
• spinner for async work
• note() for information boxes
• one question per screen

Flow: Welcome → Provider (auto-detect) → API Key (auto-detect) → Model → Embedding download → Summary → Done
