Renderers such as errorChain and the activation report expand
AggregateError members but otherwise follow only cause, so a cause of
just the setup failure hid the cleanup failure that may leave
resources alive. The cause is now an AggregateError of both failures.
An upgrade guide records that the class extends TerminalError instead
of AggregateError.
INIT_REJECTED is documented as the code a consumer that drives a shell
uses when the shell rejects its setup input, and the persistent bash
tool README records it.
