Overview

Builds a Workloads::Workload that wraps a single RSpec example.

Each call re-instantiates the example group and re-runs the example via RSpec's own Example#run(instance, reporter), which is safe to invoke repeatedly: it resets the example's execution result and exercises the full before/around/after hook chain each time (spec section 12.2, "reset workload state" + "execute measured samples"). A ::RSpec::Core::NullReporter discards RSpec's own reporting, since Baseline does its own result collection.
