//! Interactive setup wizard for IronClaw.
//!
//! Provides a guided setup experience for:
//! 1. Database connection
//! 2. Security (secrets master key)
//! 3. Inference provider selection
//! 4. Model selection
//! 5. Embeddings
//! 6. Channel configuration (HTTP, Telegram, etc.)
//! 7. Extensions (tool installation from registry)
//! 8. Heartbeat (background tasks)
//!
//! # Example
//!
//! ```ignore
//! use ironclaw::setup::SetupWizard;
//!
//! let mut wizard = SetupWizard::new();
//! wizard.run().await?;
//! ```
