## Overview

Keeps them running on `./coverage`, then swaps that to `./coverage-*`
later in the workflow.

Comparing the performance of the two end-to-end test types from `main`
(c06c62c):

| Test         | Baseline | Update   | Δ                      |
| ------------ | -------- | -------- | ---------------------- |
| `initialize` | `1m 25s` | `1m 21s` | ~0% (near zero change) |
| `migrate`    | `2m 45s` | `30s`    | 81% faster             |

Seems like this mostly improves migration. I guess initialization didn't
have this bottleneck as badlly, and still runs the initialize script
twice.
