//! `schema_dump` — full `CREATE TABLE` script for the database.
//!
//! Same output the `ask` tool feeds the LLM as ground truth, exposed
//! directly so a client can prime its own context once instead of
//! iterating `describe_table` per table. Cheap (walks `Database.tables`
//! alphabetically, formats each as a `CREATE TABLE ...;` statement).
