Adding a plugin marketplace from a link now shows a confirmation step, with new install-from-source and npm-aware install flows
What
- Adding a marketplace from a link or URL, whether via
/plugin marketplace add <path/url>or by installing a plugin from a link, now carries aconfirmAddpayload. The add-marketplace screen automatically shows a confirmation step when this hasn't been set yet but a link-based source was provided. - A new
install-from-sourceaction routes to the add-marketplace screen with plugin and link-origin details for this confirmation step. - A new
usage-errorfallback routes back to the plugin menu instead of failing silently. - Installing now short-circuits to an npm-install path when the target parses as a
plugin@npmspec.
Why
This adds a safety check before trusting and adding a marketplace source from an arbitrary link, and cleans up how installs from different kinds of sources (links, npm packages, usage errors) are routed.
