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).

Breaking changes

• 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.

New features

• 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().

Security

• 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.

Diagnostics & ergonomics

• 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.
