Add a managed-process target-lifecycle smoke group covering 1792 close cycles across Target.closeTarget, Page.close, detach-then-close, and explicit-context disposal. Synchronize on exact target and load events, preserve a live peer, and navigate over HTTP after each phase. Enforce fixed Linux FD, poll-driver, and thread budgets after warmup, persist batch samples on failure, and report unsupported external/non-Linux sampling explicitly. Include group-selection and resource-contract tests.
