/**
 * Creates a deep clone of an object or array, creating a new copy of all nested objects and arrays.
 * This function handles circular references and complex JavaScript types.
 *
 * @template T - The type of value to clone
 * @param value - The value to clone
 * @returns A deep clone of the input value
 *
 * @example
 * // Simple object cloning
 * const obj = { a: 1, b: { c: 2 } };
 * const clone = deepClone(obj);
 * clone.b.c = 3;
 * console.log(obj.b.c); // Still 2
 *
 * @example
 * // Handling arrays and nested structures
 * const arr = [1, { x: [2, 3] }];
 * const cloneArr = deepClone(arr);
 * cloneArr[1].x[0] = 10;
 * console.log(arr[1].x[0]); // Still 2
 *
 * @example
 * // Handling circular references
 * const circular = { a: 1 };
 * circular.self = circular;
 * const cloneCircular = deepClone(circular);
 * console.log(cloneCircular.self === cloneCircular); // true
