//! Database dialect abstraction for architect-sdk.
//!
//! Package configs use canonical type names (see [`types::CanonicalType`]). Each dialect
//! module maps those to database-specific DDL strings, SQL casts, and operator rules.
//!
//! # Adding a new dialect
//! 1. Add a Cargo feature (e.g. `mysql`).
//! 2. Create `src/db/your_dialect.rs` implementing [`Dialect`].
//! 3. Gate it with `#[cfg(feature = "your_dialect")]` below.
//! 4. Add it to `active_dialect()`.
//! 5. Add to Cargo.toml features.
