 * @returns An object containing methods to manipulate cookies:
 *  - `setCookie`: Sets a cookie with the specified name, value, and options
 *  - `getCookie`: Retrieves a cookie value by name
 *  - `removeCookie`: Removes a cookie by name
 *  - `getKeys`: Gets an array of all cookie names
 *
 * @example
 * ```typescript
 * const { setCookie, getCookie, removeCookie, getKeys } = useCookie();
 *
 * // Set a cookie
 * setCookie('user', 'john', { expires: 7 });
 *
 * // Get a cookie
 * const value = getCookie('user');
 *
 * // Remove a cookie
 * removeCookie('user');
 *
 * // Get all cookie names
 * const cookieNames = getKeys();
 * ```
