Module handlers 

Axum handlers for the three public endpoints.

All handlers are async, but every one that touches the database delegates SQLite work to AppState::with_connection, which runs on Tokio’s blocking-task pool. The handlers themselves do parsing, parameter validation, and response shaping — nothing else.

GET /version is the exception: it returns compile-time constants only and never opens the database.
