Add Superpowers Chinese marketplace plugin

Constraint: Keep the official Superpowers plugin available under its existing ID while publishing the localized fork with a distinct ASCII ID.

Rejected: Reusing the upstream superpowers manifest name | It collides with the official marketplace entry.

Confidence: high

Scope-risk: narrow

Directive: Continue syncing this plugin from AreChen/superpowers-zh and preserve hooks: {}.

Tested: Marketplace validator, Codex local install/list/remove, KeyInfo adapter tests, upstream Codex manifest and package checks except its platform-specific tar epoch assertion.
