/**
 * Creates an object with the same keys as the given object, but
 * with values transformed by the provided function.
 *
 * @param object - The source object.
 * @param function_ - The function invoked per value. Receives (value, key).
 * @returns A new object with transformed values.
 *
 * @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)
 *
 * @example
 * ```typescript
 * mapValues({ a: 1, b: 2 }, (value) => value * 2);
 * // { a: 2, b: 4 }
 * ```
