[documentation] Missing package documentation

[docker-agent]

🟠 high - documentation

File: cmd/root/root.go (line 1)

Code

package root

Problem

The cmd/root package has no package-level documentation comment explaining its purpose and exported API.

Suggested Fix

Add a package documentation comment at the top of root.go explaining that this package contains the CLI command structure and root command initialization.
