/**
 * A migration class name carries its own creation timestamp - `SomeName_yyyy_MM_dd_HH_mm_ss` -
 * and that timestamp is the only ordering the runner has.
 *
 * Lives here rather than in `migration-runner.ts` ( which re-exports it for its existing public
 * import path ) because this module is a leaf with zero relative imports. `migration-runner.ts`
 * sits in a require cycle with `orm.ts`, reaching it through `migration-service.js`, `driver.js`
 * and onwards, while `migration-environment.ts` ( which also needs this regexp ) is itself
 * required BY `orm.ts`. Importing it from the runner would close that cycle one hop earlier.
