Module schema_metadata 

Static metadata for downgrade planning.

Migrator::migrations() owns the executable migration order. This module keeps the user-facing downgrade metadata in the same crate so release checks can ensure every migration has an explicit reversibility and cache-impact decision before a new binary ships.
