* Failed plugin installs notice for the Setup Wizard.
*
* The wizard installs cross-product plugins and addons in the background. When
* an installation fails, the plugin files and their error messages are parked in a
* week-long transient here. After the wizard finishes, a dismissible admin notice
* naming the failed regular plugins, each linked to its WordPress.org repository
* page, is shown on WPForms admin pages (the form builder excluded) so the user
* can install them manually. The transient TTL lets the notice fade on its own
* after a week when it is never dismissed, and the next wizard launch clears it so
* a fresh run never inherits stale failures.
*
* Failed addons are handled by the Pro subclass, which adds its own dismissible
* notice (see {@see \WPForms\Pro\SetupWizard\FailedInstallsNotice}).
