/**
 * Creates a deep clone of an object, array, or primitive value.
 * Handles nested objects and arrays recursively.
 *
 * @template T - The type of value to clone
 * @param value - The value to clone
 * @returns A deep clone of the value
 *
 * @example
 * ```ts
 * const obj = { a: 1, b: { c: 2 } };
 * const cloned = deepClone(obj);
 * cloned.b.c = 3;
 * console.log(obj.b.c); // 2 (original unchanged)
 * ```
