/**
 * Extracts the pathname from a full URL string.
 *
 * This function avoids using `URL` constructor for performance and compatibility
 * and instead uses low-level string operations. It is designed to handle URLs like:
 * - `http://example.com/path/to/resource?query=1`
 * - `https://example.com/`
 * - `http+unix://%2Fpath%2Fto%2Fsocket:/request/path`
 *
 * If the pathname cannot be found, it defaults to `/`.
 *
 * @param {string} url - The full URL string to parse.
 * @returns {string} The extracted pathname, or `/` if not found.
 *
 * @example
 * getPathname("https://example.com/page?name=test")
 * // returns "/page"
 *
 * @example
 * getPathname("http://localhost/")
 * // returns "/"
 *
 * @example
 * getPathname("http+unix://%2Ftmp%2Fsocket:/api/test")
 * // returns "/api/test"
