Working title: urfave/cli vs cobra, when to pick which

Hook: Two Go CLI frameworks dominate the ecosystem. Most people pick cobra by default. Here is the case for urfave/cli, the case for cobra, and the actual decision criteria, from a former urfave/cli maintainer.

Beats:

The split-brain in the Go CLI world.
urfave/cli's design choices (flag-first, middleware, no global state).
cobra's design choices (command-first, viper-coupled, generators).
What each is good at; what each is bad at.
Concrete decision matrix: small operator CLI, large multi-command tool, plugin host, kubectl-shaped.
Honest take on the maintainer experience and what's coming next in v3.

Why now: leans on credentials nobody else in the comparison space has. Cheap to write because the opinions are already formed.

Audience: Go programmers writing CLIs. Wide and persistent audience.
