//! Purpose: Directory-backed facade for config migration helpers.
//!
//! Responsibilities:
//! - Declare focused config migration companion modules.
//! - Re-export the stable config migration API used by migration dispatch code.
//! - Keep regression coverage colocated with the facade.
//!
//! Scope:
//! - Thin facade only; key detection, key rewrite, CI gate migration, and legacy
//! contract upgrade behavior live in companion modules.
//!
//! Usage:
//! - Imported through `crate::migration::config_migrations::*` by `migration::mod`.
//!
//! Invariants/Assumptions:
//! - Public signatures remain stable across this split.
//! - JSONC-preserving key rename behavior remains unchanged.
//! - Companion modules stay private to the migration boundary.
