Research direction

Locate the stage hook execution path and compare the existing sequential path behind the toggle with the concurrent path. Read the linked config.md and runtime.md requirements first; done means hooks run in listed order and a failing createRuntime, createContainer, or startContainer hook prevents later hooks and stops the container, with the concurrent path removed.

Written by the indexing model from the issue text.

Description

We currently run each stage's hooks concurrently, one goroutine per hook. So when a stage has more than one hook they don't run in listed order, and a failing hook doesn't stop the ones after it. The spec requires both: hooks "MUST be called in the listed order" (config.md), and a failing createRuntime/createContainer/startContainer hook MUST stop the container (runtime.md).

The sequential path already exists in the tree behind a toggle. Since the concurrency only matters when a stage has 2+ hooks, exactly the case it gets wrong, we can just run them sequentially and drop the concurrent path, which also retires the panic #445 fixed inside it.
