/**
 * Boot migration: strip the legacy 'files/' prefix from trip_files.filename.
 *
 * Collab note attachments historically stored 'files/<name>' while the file
 * manager stored bare names in the same column; the storage layer addresses
 * objects as category + bare name, so existing prefixed rows are normalized
 * once at boot (storage slice 2). Ported off the legacy runner (Task 0
 * triage: PORT) onto the real `Migration20200101031600_storage_slice_2`:
 * migrate to the step immediately before it, seed rows with raw SQL, apply
 * just that one migration, assert.
