MultiGrantFakeManager

A GrantManager fake that behaves statefully across calls, unlike FakeGrantManager.

Calling request doesn't just return a canned value — it writes the result back into the status map, so a subsequent checkStatus for the same permission sees the post-request state. This matters for tests of code that requests a permission and then immediately re-checks it (e.g. a dev.brewkits.grant.GrantGroupHandler driving several permissions and re-evaluating which ones are still outstanding), where FakeGrantManager's stateless per-call return values would make every re-check look identical to the first one.

Prefer FakeGrantManager for most tests — reach for this one specifically when the behavior under test depends on status changing as a consequence of a request, not just on what the request returns.
