daemon-auth (compat shim)

This crate is a backward-compatible re-export of auth-engine. New code should depend on auth-engine directly.

Authentication and session management for the daemon.

Purpose

Handles OAuth login flow, token refresh, and session state. Integrates with Supabase for device registration and session secret management.

Key Features

• OAuth flow: Local HTTP callback server for browser auth
• Token refresh: Automatic background token renewal
• FSM-based state: Explicit auth state machine (logged out → authenticating → authenticated)
• Supabase client: Device and session secret API calls
