/**
 * Normalizes a server URL for credential-binding comparison. The
 * canonical `URL.href` form lowercases the host, drops a default port,
 * and adds the trailing slash of an origin URL, so equivalent spellings
 * compare equal. A trailing slash on a non-origin path stays
 * significant: `https://example.com/mcp` and
 * `https://example.com/mcp/` are different endpoints.
 *
 * @param url - The server URL to normalize.
 * @returns The normalized URL, or undefined when the input is absent or
 *   not a valid absolute URL.
