1//! Extension registration for the database crate's own schema.
2//!
3//! Every systemprompt extension that owns DDL registers itself through the
4//! `inventory` framework. The database crate registers its own bookkeeping
5//! tables (`extension_migrations`) and shared SQL helper functions so that
6//! they install before any downstream extension runs.
