[Bug]: Error log message is misleading: `handler for snapshotGet threw error notFound: "image snapshot for ref"`

[jglogan]

I have done the following

• I have searched the existing issues
• If possible, I've reproduced the issue using the 'main' branch of this project

Steps to reproduce

Run container system logs, and run any image that's not been unpacked yet.

Current behavior

The logs will container something like.

2025-09-03 17:06:04.702630+0800 0x3adf     Error       0x0                  1099   0    container-core-images: [com.apple.container:ImagesHelper] handler for snapshotGet threw error notFound: "image snapshot for docker.io/library/ubuntu:24.04 with platform linux/amd64"

That this is listed as an error is misleading. It just means the image hasn't been unpacked yet.

Expected behavior

No error at this point. Arguably this message is simply noise in this context.

Environment

- OS: 26 beta
- Xcode: 26 beta
- Container: 0.4.1
