feat: Add Employee class with encapsulation and overridden toString() method

- Implemented a basic `Employee` class with two private instance variables: `id` and `name`
- Provided public getter and setter methods for both fields, ensuring proper encapsulation
- Overrode the `toString()` method from `Object` class to return a meaningful string representation of an Employee object (`"id name"`)
- Demonstrated usage in the `main` method by:
  - Creating an `Employee` object
  - Setting values using setter methods
  - Printing the object reference, which internally invokes the overridden `toString()` method

This commit highlights how `toString()` can be customized to improve object representation for debugging, logging, or output readability.
