| * Returns a stable callback function whose identity does not change between renders, | |

| * This is useful when you need to pass a callback to a dependency array or a child component, | |
| * and want to avoid unnecessary re-renders or effect executions caused by changing function references, | |
| * while still ensuring the callback always has access to the latest props and state. | |

| * @param callback - The callback function to be stabilized. | |
| * @returns A stable function that always calls the latest version of the provided callback. | |
