- When pulling warmup images for concurrent tests, save
the images to a cache directory under the application root.
- Serial tests that aren't testing pull can save time by restoring
a cached warmup image.
- Part of #1833.
- Adds `ContainerFixture` with scoped resource lifecycle and cleanup in
place of implementation inheritance for test support functions. The
fixture also handles resource prefixing and uses a more ergonomic
`CommandResult` in place of a tuple for return values.
- `ImageWarmup` suite pre-pulls well-known images, and
`copyWarmupImage()` tags test-local refs, keeping the canonical image
store untouched.
- Three-phase `integration-new`: warmup, followed by concurrent tests
(managed by the swift test
`--experimental-maximum-parallelization-width` flag), followed by
serialized tests.
- `coverage-new` merges unit + integration-new profraw, replacing
`coverage` in CI as a migration progress indicator.
- Updates GH workflow so non-coverage invokes both the `integration` and
`integration-new` Makefile targets, while coverage runs invoke the
`coverage-new` target.
