linkerd/linkerd2 — reverse-engineered prompt

Build me a lightweight, security first service mesh for Kubernetes, basically something in the spirit of Linkerd 2.x. I want it to be easy to install on a modern cluster and give me the core value without needing to change my app code.

Please include the main pieces a real user would expect, a CLI to install, upgrade, check status, and remove it, a control plane that runs in the cluster, and a simple web based view for observability so I can see service health and traffic at a glance. The big goals are secure service to service communication, better reliability, and useful visibility into what is happening between workloads.

Keep it practical and developer friendly. It should feel fast, small, and production minded, not like a huge complicated platform. If there are charts or manifests needed to deploy it, wire those up too. Good defaults matter. If you need details, look up the current Linkerd docs online and mirror the overall experience closely.
