helm/helm ? reverse-engineered prompt

Build me a command line tool for Kubernetes that works like a package manager, so I can install, upgrade, roll back, and remove apps using reusable chart packages.

I want it to let people package an app with a simple chart file and template files, then render those templates into Kubernetes manifests and apply them to a cluster through the Kubernetes API. It should be able to use charts from disk or from a remote chart repository, and it should keep track of releases so users can manage versions cleanly.

Make it feel polished and usable from a laptop or in CI, with helpful commands like install, search, list, upgrade, rollback, and uninstall. Include the basic docs and examples so someone can quickly try it with a sample chart. If you need to check current Kubernetes or Go docs while building it, go ahead and look them up online.
