### What changes were proposed in this PR? `CheckpointSpec` was the slowest spec in CI (~70s for 2 trivial assertions) because it booted **two** Pekko `ActorSystem`s: - one in `beforeAll` (`CheckpointSpec.scala:62`) - a second one created lazily inside `AmberRuntime.serde` when `chkpt.save(...)` was first called The two systems never interacted — the second only existed so `SerializationExtension` had a system to attach to. This PR adds an `actorSystem_=` setter on `AmberRuntime` and uses it in `CheckpointSpec.beforeAll` to hand the spec's own system to the runtime, so the lazy fallback never fires. Long-stale commented-out tests in the same file are also dropped. ### Any related issues, documentation, discussions? Closes #4501 ### How was this PR tested? Existing `CheckpointSpec` tests cover the two assertions. Verified locally that the spec still completes the same two assertions; relying on CI to confirm full timing improvement. ### Was this PR authored or co-authored using generative AI tooling?
