Implement ARM test which runs examples

* Test if examples can be run with a local installer.
* Test with a explicit working directory and with a temp directory automatically created by the ACPWorkflow class.

Start by reviewing the example workflows and the local installer behavior, then inspect the ACPWorkflow class to understand its temporary-directory handling. Add ARM tests covering example execution with an explicit working directory and with an automatically created temporary directory; done means both scenarios run successfully.
