Overview

Shared child-process lifecycle for running an isolated RSpec run: spawns (via a subclass's #start), reaps with a timeout budget (TERM then KILL on overrun), and hands the captured output/JSON to Result. Subclasses (ForkStrategy, SpawnStrategy) only implement how the child is started.

Direct Known Subclasses
