Six suites build a real DB under a temp dir and then `rmSync` it in
`afterEach`. Each leaked its own one-shot statement the same way the source
did, so the teardown hit EBUSY on Windows and failed tests whose assertions
had already passed.
Only the suites that touch a file-backed DB are changed. The remaining
`prepare()` calls in the package tests run against `:memory:`, where there
is nothing to unlink and no cleanup to fail.
