 * Plugins: Settings › Plugins (installed list, enable/disable, install from

 *
 * Actions: `plugins.settings`, `plugins.installFromDisk`, `plugins.reloadAll`,
 * plus one action per plugin command: `plugin.<pluginId>.<commandId>`
 * (searchable in Search Everywhere › Actions and bindable in the keymap editor;
 * a string arg is forwarded to the plugin).
 *
 * Editor contribution `plugins.lineMarkers`: gutter icons from plugin
 * `line-markers` providers (`lineMarkerGutter.ts`).
