 * Decorator that assigns metadata to the class/function using the

 * Requires two parameters:
 * - `key` - a value defining the key under which the metadata is stored
 * - `value` - metadata to be associated with `key`

 * This metadata can be reflected using the `Reflector` class.

 * Example: `@SetMetadata('roles', ['admin'])`
