Module migration 

Purpose: Provide the public migration API surface and top-level orchestration.

Responsibilities:

• Declare migration companion modules.
• Re-export migration data models and context types.
• Check, apply, and list migrations without owning leaf migration logic.

Scope:

• Top-level orchestration only; type definitions live in types.rs, history persistence lives in history.rs, and leaf migration behavior lives in config_migrations/ and file_migrations/.

Usage:

• Import migration helpers through crate::migration.
• Internal modules may use the re-exported types or sibling companion modules.

Invariants/Assumptions:

• Re-exports preserve existing caller imports.
• Migrations remain idempotent and registry-driven.
• Migration history is saved immediately after each successful apply.
