…, use it in integration test cleanup (#4587) This attempts to fix some of the residual flakiness encountered in #4570 Somehow the recursive process termination we pulled in from upstream com-lihaoyi/os-lib#359 only works some of the time, and other times the processes get leaked. This PR extends the `serverId`-file-deleted shutdown logic we already used for client-server mode and enables it for `--no-server` mode as well. This lets us put an additional guardrail in our `IntegrationTester#close` to delete any such files, to try and force any Mill processes to terminate. Added an additional integration test to exercise this behavior Also fixed a bug in `ExampleTester` not honoring the `clientServerMode` flag, and update `testkit.test` to assert on those behaviors

bincompatforwarders were incorrectly settingdestroyOnExit = falsewhen the default istrue, this makes them consistently passdestroyOnExit = falsewhen an explicit value is not providedos.proc.callwas forgetting to forwardshutdownGracePeriodanddestroyOnExitto the underlyingos.proc.spawnSubProcess#destroywas not destroying descendent processes. While this has always been the default, it has always been confusing, and often resulted in leaking orphan processes. This PR makes it recursively destroy child processes by default, unless passedrecursive = false.destroyOnExitand on timeout now is always recursiveDropping Scala-Native support for now due to:
Will open an issue to figure it out asynchronously
