reactRouter 0.2.0

CRAN submission. Major release upgrading the package to React Router v7 with the data router API (loaders, actions, fetchers, deferred data).

RouterProvider() now takes a router argument built with create*Router() instead of route children.
data() was renamed to dataResponse() and replace() was renamed to replaceResponse() to avoid masking base R functions.
reloadDocument on Link() / NavLink() defaults to FALSE.

Updated to React Router v7 (react-router-dom 7.x).
Data router API: createBrowserRouter(), createHashRouter(), createMemoryRouter() paired with RouterProvider(router = ...) — the recommended way to use loaders, actions, fetchers, and Await.
New components: Await, Form, ScrollRestoration, Outlet, Routes, Navigate.
New hooks: useLoaderData, useActionData, useNavigation, useNavigate, useNavigationType, useMatch, useMatches, useSearchParams, useRouteError, useRouteLoaderData, useFetcher, useFetchers, useRevalidator, useBlocker, useSubmit, and more.
New loader/action helpers: redirect(), replaceResponse(), redirectDocument(), dataResponse().

redirect(), replaceResponse(), and redirectDocument() reject unsafe URL schemes (javascript:, data:, vbscript:) and protocol-relative targets.
reactRouterExample() validates example against the list of bundled examples, closing a path-traversal vector in user-supplied input.
New vignette: “Security considerations” — guidance on loaders/actions as client-side code, URL-encoding route params, redirect targets, CSP, and more.

Route() validates that loader and action inherit from JS_EVAL at call time, surfacing a common mistake before it becomes a browser-side error.
dataResponse(): value is now a required argument.
useNavigate(), useSubmit(), and useLinkClickHandler() refuse into= with as = "children" and point to render = JS(...) or as = "onClick" — these hooks return functions, not renderable children.
RouterProvider logs a dev-mode warning when the route tree changes after mount; remount via a key prop to apply new routes.

BREAKING CHANGE: reloadDocument is now FALSE by default (like in React Router 6.30.0)
added data loader and hooks
improve examples and docs
