Description:
Implement Docker image management for packages requiring containerized dependencies.

Acceptance Criteria:

• DockerInstaller class with multi-registry support (Docker Hub, GHCR, custom registries)
• Registry authentication working for private repositories
• Image signature verification where available (Docker Content Trust)
• Container lifecycle management integration with existing tool execution
• Security scanning using trivy or equivalent for vulnerability detection
• Image caching and cleanup policies to manage disk space
• Tests with examples from multiple registries, the security scans, and the caching/cleanup... Basically everything!

Dependencies:

• Requires Issue Abstract Dependency Installer Architecture #7
