 * * Utility to generate query parameters from an object.

 * @returns A query string as a URL-encoded string, e.g., `?key1=value1&key2=value2`.
 *
 * @example
 * generateQueryParams({ key1: 'value1', key2: 42 }); // "?key1=value1&key2=42"
 * generateQueryParams({ key1: ['value1', 'value2'], key2: 42 }); // "?key1=value1&key1=value2&key2=42"
 * generateQueryParams({ key1: '', key2: null }); // ""
 * generateQueryParams({ key1: true, key2: false }); // "?key1=true&key2=false"
 * generateQueryParams({ filters: { category: 'laptop', price: 1000 } }); // "?category=laptop&price=1000"

 * Parses a query string (with optional `?` prefix) into an object.
 * Supports multiple values for the same key by returning arrays.
 * Optionally parses primitive string values into actual types (e.g., "1" → 1, "true" → true).
 *
 * - **Note:** *This function does **not** access or depend on `current URL` a.k.a `window.location.search`.*
 *
 * @param query - The query string to parse.
 * @param parsePrimitives - Whether to convert stringified primitives into real values (default: true).
 * @returns An object where keys are strings and values can be string, array, number, boolean, or null.
