/**
 * Manages the registration and lookup of connectors.
 *
 * This is an internal class. Use the public API functions to interact with connectors:
 *
 *  - `wp_is_connector_registered()` — check if a connector exists.
 *  - `wp_get_connector()`           — retrieve a single connector's data.
 *  - `wp_get_connectors()`          — retrieve all registered connectors.
 *
 * Plugins receive the registry instance via the `wp_connectors_init` action
 * to register or override connectors directly.
