描述

Feature or enhancement request details

When saving an image pulled from remote sources, if the platform is nil, the save will failed with the notFound error:

For example, running

container image save alpine:latest --output /Users/itsuki/Desktop/untitled\ folder/image.tar

will give

Error: notFound: "Content with digest sha256:eafc1edb577d2e9b458664a15f23ea1c370214193226069eb22921169fc7e43f"

The digest here is not the digest for the image we are trying to save specifically, but the same for any (I think) remote images.

However, specifying the platform to be the current platform, in my case, --platform linux/arm64/v8, the save will success.

研究方向
Investigate the `image save` command implementation in the repository. Look for where the platform parameter is handled and where a default platform should be set to the current system platform (e.g., via runtime detection or configuration). Check the error message to identify the source of the notFound digest mismatch. Consider adding a fallback to the current platform when nil is provided, similar to how other commands might default. Relevant files could be in the command handler or platform resolution logic.
