// Contract test for the prompts the plugin-folder card buttons send to the
// agent. `install` uses the simple shared template; `contribute` drives the
// `gh repo fork → branch → commit → gh pr create --web` flow against
// `nexu-io/open-design`; `publish` drives `gh repo create / push` against the
// author's own `plugin.repo` URL. The tests below lock the *shape* of each
// prompt (keywords + folder interpolation) without coupling to exact wording,
// so prose tweaks don't break the suite but accidental removal of a critical
// step would.
