/**
 * Checks if a remote resource is accessible by performing a lightweight fetch.
 *
 * This function uses the `fetch` API with the 'GET' method and an AbortController
 * to efficiently validate a source URL. It only waits for the response headers;
 * upon receiving a successful status code, it immediately aborts the download of
 * the response body to save bandwidth. It maps HTTP status codes and network
 * errors to a `ValidationStatus` enum.
 *
 * @param {string | undefined} source The URL of the resource to validate.
 * @returns {Promise<ValidationStatus>} A promise that resolves to a `ValidationStatus`
 * enum value indicating the outcome of the validation check.
