What's New

• Adds attestation list and get commands for managing attestations
• Adds SBOM subcommand for software bill of materials attestation
• Adds bulk support to prepare command for customizations
• Adds compression field support for customizations

Breaking change

We removed the --output flags from the few commands that had it (customization prepare and customization get) in favor of stdout redirections.

# before
dhictl customization prepare --org my-org golang 1.25 --output my-customization.yaml

# after 
dhictl customization prepare --org my-org golang 1.25 > my-customization.yaml
