Description

Hello there,

I would like to see a download command added to packer to only download and check the ISO file without starting to build anything. The idea behind this feature request would be to be able to automatically (using a CI service for example) check if the ISO file used by a template is still available (to avoid dead links).

I look forward to your feedback on this feature.

Cheers.

Research direction
Investigate the existing packer command structure, particularly the build command, to understand how commands are registered and executed. Review the comments in this issue for any maintained suggestions or concerns. Consider adding a new command that reuses the ISO download logic from the build process without initiating a full build.
