// TestMain puts a silent docker stub on PATH for every test in this package: R-650, the fixtures
// here build a real stacks.Manager, and on the build host (DooPlex) that reached production Docker.
//
// R-751: the retention after an update or a remove runs in a GOROUTINE that outlives the test that triggered it — it
// wrote into a test's temp dir while the dir was being removed ("directory not empty") and once panicked on the
// vanished stack. No test here may leave one running: both seams are no-ops by default; the retention tests call
// RetainImagesAfter* directly, and the wiring tests swap the seams themselves.
