/**
 * @fileoverview The graphical install's screens in the Codeman Desktop connect page, and the This
 * Mac tab's rows for the Codeman servers the app found on this Mac.
 *
 * Runs the real packages/desktop/assets/connect.html in jsdom with a fake native side:
 * `window.ipc` records what the page asks the app for, and `onNative` is what the app
 * calls. The Rust side of the same messages is pinned in packages/desktop/src/policy.rs
 * (`ipc_graphical_install_commands`), src/gui_install.rs and src/setup.rs (the `found` list:
 * `a_found_server_row_says_what_answered`), which do not build on Linux CI, so the spelling of
 * every message the page sends, and of what it reads, is asserted here.
