/**
 * Starts the static site parts of the plugin. The FlyWP app builds the static copy. The plugin gives it the site data.
 *
 * - register_cli(): the WP-CLI commands `flywp static site` and `flywp static changes clear`. It runs also
 *   when no FLYWP_API_KEY is set.
 * - The constructor (site with an API key): records content changes when the option flywp_static_enabled is 1.
 * - The change log table: installed on plugin activation, and on a version change in wp-admin, REST requests
 *   and WP-CLI. Never on a normal front-end request.
