/**
 * Creates a deep clone of the given value.
 *
 * @param value - The value to deep clone.
 * @returns A deep clone of the input value.
 *
 * @example
 * ```typescript
 * const original = { a: 1, b: { c: 2 } };
 * const cloned = deepClone(original);
 * cloned.b.c = 99;
 * original.b.c; // still 2
 * ```
 *
 * @remarks
 * **Prototype pollution warning:** This function does not filter out
 * prototype-polluting keys (`__proto__`, `constructor`, `prototype`).
 * If processing user-controlled input, sanitize with the appropriate
 * `removePrototype*` helper before calling this function:
 * - `removePrototype` — shallow sanitization of a single object
 * - `removePrototypeDeep` — recursive sanitization of a single object (for deeply nested data)
 * - `removePrototypeMap` — shallow sanitization of an array of objects
 * - `removePrototypeMapDeep` — recursive sanitization of an array of objects (for deeply nested data)
