1//! `std.sql` thin adapter.
2//!
3//! Bridge implementation moved to the `mlua-batteries` crate
4//! (`mlua_batteries::sql`).  This module only resolves the host's
5//! environment-driven SQL configuration into a
6//! [`mlua_batteries::sql::SqlConfig`] before delegating to
7//! [`mlua_batteries::sql::register_with`], then layers the agent-block
8//! Lua tool helpers (`sql_tools.lua`) on top.
9//!
10//! See `bridge/config.rs` for the ENV → config mapping.
