* test: add a failing test * feat: add no_tx to migration struct * feat: execute migration with no tx block * fix: expected string literal compilation error * test: update no tx to content comment * refactor: use the sql comment instead of file name semantics * docs: remove no_tx from file format comment * fix: remove filename matches * fix: messed up merge * refactor: dedupe migration * fix: move comment to where it makes sense * fix: linter error
