/**
 * Custom hook to manage tab state via URL search parameters in a Next.js application.
 * This hook allows for syncing the active tab with the browser's URL, enabling bookmarking and sharing of URLs with a specific tab activated.
 *
 * @param {UseTabSearchParamsOptions} options Configuration options for the hook:
 * - `defaultTab`: The tab to default to when no tab is specified in the URL.
 * - `routingBehavior`: Optional. Determines how changes to the active tab update the browser's history ('push' or 'replace'). Default is 'push'.
 * - `searchParamName`: Optional. The name of the search parameter that holds the tab state in the URL. Default is 'category'.
 * @returns A tuple where the first element is the active tab and the second element is a function to set the active tab.
