minihubd — minihub daemon

Composition root that wires all adapters together and starts the server.

Responsibilities

• Parse configuration (CLI args, env vars, config file)
• Initialize the SQLite connection pool and run migrations
• Construct repository implementations (adapters)
• Construct application services, injecting repositories via port traits
• Build the axum router, injecting application services
• Bind to a TCP port and serve
• Handle graceful shutdown (SIGTERM/SIGINT)

Dependency rule

This is the only crate that depends on all other crates. It is the wiring layer — no domain logic belongs here.
