v6: Retire the composable GraphiQL.Toolbar and GraphiQL.Logo slots (#4425)

## Summary

- Remove the composable `GraphiQL.Toolbar` and `GraphiQL.Logo` slots.
#4398 already stopped rendering their v5 defaults, leaving them in an
awkward half-fit spot with nowhere natural left to render; this finishes
the job by removing the slots themselves.
- `GraphiQL.Toolbar` is a straight removal, no deprecation period first.
Custom editor actions belong on a plugin's `sessionActions` now,
rendered into the tab strip alongside Prettify/Merge/Copy/Save.
- `GraphiQL.Logo` is removed now that `<TopBar>` takes a new `brand`
prop (any `ReactNode`), which is also exposed straight off `<GraphiQL>`.
It replaces the default hexagon icon + "GraphiQL" wordmark; leave it
unset to keep the default.
- `GraphiQL.Footer` is untouched.
- Also drops the dead
`toolbar.additionalContent`/`toolbar.additionalComponent` `TypeError`
guards, since they pointed at the component being removed here, and the
`.graphiql-toolbar`/`.graphiql-logo` CSS those slots used.
- Updates the README and the v6 migration guide with before/after
snippets, and migrates the `graphiql-vite-react-router` example off both
slots.

Builds on #4398.

## Test plan

- [x] Render `<GraphiQL>` with no extra props. The top bar shows the
default hexagon icon and "GraphiQL" wordmark.
- [x] Render `<GraphiQL brand="My Company">`. The top bar shows "My
Company" instead, and the default wordmark is gone.
- [x] Confirm the old `GraphiQL.Toolbar`/`GraphiQL.Logo` slots are gone:
referencing `<GraphiQL.Toolbar>` or `<GraphiQL.Logo>` as JSX children is
now a TypeScript error, and there's no runtime path that renders them.
- [x] Confirm toolbar actions still work from the tab strip: Prettify,
Merge Fragments, Copy, and Save each appear once and behave as before.
- [x] Register a plugin with a `sessionActions` component and confirm it
renders in the tab strip alongside the built-in actions.
- [x] Confirm `<GraphiQL.Footer>` still renders below the response,
unchanged.
- [x] Run the `graphiql-vite-react-router` example and confirm the
branding shows "API Explorer" and the share-query button still works
from the tab strip.

 # Upgrading `graphiql` to `6.0.0`
 
-GraphiQL 6 is a visual redesign built on a new OKLCH color system, plus a handful of mostly additive API changes: a `Transport` API that sits alongside the existing `Fetcher`, a settings dialog for theme/density/font-size, and two new first-party plugins (a visual query builder and operation collections) installed by default. The one breaking change is that the hooks deprecated in v5 are now removed, each with a drop-in replacement.

 ## Overview
 
 Visually, v6 introduces a new OKLCH-based design-token system, restyles every primitive component (buttons, dialogs, tabs, dropdowns, tooltips), and reworks the app chrome around a top bar, an activity rail, and a side panel. Functionally, the biggest changes are a new `Transport` API for the network layer, the active operation following your cursor instead of only updating on run, and two new default-installed plugins: a visual query builder and operation collections.
 
-Most of this is additive and requires no rewrite: the old `fetcher` prop and the old CSS variables keep working. The one breaking change to watch for is the removal of the hooks that were deprecated back in v5 (`useEditorContext`, `usePluginContext`, and the rest). Each has a direct replacement, covered below. Read the sections relevant to your setup and treat the rest as optional cleanup.

+## Removed `GraphiQL.Toolbar` and `GraphiQL.Logo`
+
+`<GraphiQL.Toolbar>` and `<GraphiQL.Logo>` are removed. Both were compound-component children you passed to `<GraphiQL>` to customize the editor toolbar and the corner branding; in v6 those render sites don't exist anymore (the toolbar's default prettify/merge/copy actions and the corner logo were already removed from the default render in a prior v6 change), so the slots had nowhere natural left to render. `<GraphiQL.Footer>` is unchanged and still works exactly as before.
+
+### `GraphiQL.Toolbar` → plugin `sessionActions`
+
+Custom editor actions now live in the tab strip, next to prettify/merge/copy/save, through a plugin's `sessionActions`: an always-mounted component every registered plugin can provide, regardless of whether that plugin's pane is visible.
+
+**Before:**
+
+```tsx
+import { GraphiQL } from 'graphiql';
+import { ToolbarButton } from '@graphiql/react';
+
+function App() {
+  return (
+    <GraphiQL fetcher={fetcher}>
+      <GraphiQL.Toolbar>
+        {({ prettify, merge, copy }) => (
+          <>
+            {prettify}
+            {merge}
+            {copy}
+            <ToolbarButton label="My custom action" onClick={onClick} />
+          </>
+        )}
+      </GraphiQL.Toolbar>
+    </GraphiQL>
+  );
+}
+```
+
+**After:**
+
+```tsx
+import { GraphiQL } from 'graphiql';
+import { HISTORY_PLUGIN } from '@graphiql/plugin-history';
+import { QUERY_BUILDER_PLUGIN } from '@graphiql/plugin-query-builder';
+import { collectionsPlugin } from '@graphiql/plugin-collections';
+import { ToolbarButton, type GraphiQLPlugin } from '@graphiql/react';
+
+const myActionsPlugin: GraphiQLPlugin = {
+  title: 'My Plugin',
+  icon: MyIcon,
+  content: MyPluginPanel,
+  sessionActions: () => (
+    <ToolbarButton label="My custom action" onClick={onClick} />
+  ),
+};
+
+function App() {
+  return (
+    <GraphiQL
+      fetcher={fetcher}
+      plugins={[
+        HISTORY_PLUGIN,
+        QUERY_BUILDER_PLUGIN,
+        collectionsPlugin(),
+        myActionsPlugin,
+      ]}
+    />
+  );
+}
+```
+
+Prettify, merge, and copy no longer need re-wiring: they're built into the tab strip by default. Passing the `plugins` prop replaces the default-installed plugin set (as it always has), so include the ones you still want (`HISTORY_PLUGIN`, `QUERY_BUILDER_PLUGIN`, `collectionsPlugin()`) alongside your own.
+
+### `GraphiQL.Logo` → the top bar's `brand` prop
+
+Branding is customized through a `brand` prop passed straight to `<GraphiQL>` (or to `<TopBar>` directly if you're composing your own layout with `GraphiQLInterface`). It accepts any `ReactNode` and replaces the default hexagon icon + "GraphiQL" wordmark; leave it unset to keep the default.
+
+**Before:**
+
+```tsx
+<GraphiQL fetcher={fetcher}>
+  <GraphiQL.Logo>My Company</GraphiQL.Logo>
+</GraphiQL>
+```
+
+**After:**
+
+```tsx
+<GraphiQL fetcher={fetcher} brand="My Company" />
+```
+
+`brand` isn't limited to text — pass any element, like your own logo image alongside a label.
+
 ## New `transport` prop
 
 `@graphiql/toolkit` adds `createTransport`, which takes the same options as `createGraphiQLFetcher` and produces a `Transport`. Unlike `Fetcher`, a `Transport`'s response carries the real HTTP wire data: status code, headers, body, timing, and request/response sizes. `<GraphiQL>` accepts a new `transport` prop alongside the existing `fetcher` prop; the two are mutually exclusive at the type level. The old API still works, unchanged.
