docs(content): align user docs site with the 11 breaking changes

Sweep of content/docs/** (the docs.objectstack.ai site) for symbols/packages
removed in 11. ADRs/audits and metric names (http_requests_total) left as-is;
service-ai references kept (correctly documented as cloud/Enterprise).

- packages.mdx + concepts/packages.mdx: Framework Adapters → Hono-only; removed
  the 6 non-Hono adapter sections, the plugin-msw sections, and fixed the
  dependency ASCII tree.
- deployment-vercel.mdx: removed the broken Next.js "Option A" (@objectstack/nextjs);
  Hono is the server path; intro reframed + a callout flags the removed MSW mode.
- environment-variables.mdx: alias table reframed (ecosystem names permanent/silent;
  OS_MULTI_TENANT / OBJECTSTACK_METADATA_WRITABLE / AUTH_BASE_URL removed-in-11 note).
- one-liners: flow.mdx / business-logic.mdx (http_request→http), client-sdk.mdx
  (query aliases removed), metadata-service.mdx (IUIService removed),
  references/index.mdx (PolicySchema row), plugins.mdx (plugin-msw), schema.mdx /
  security.mdx / adding-a-metadata-type.mdx (env renames), authentication.mdx
  (removed the MSWPlugin browser-kernel example).

Deferred (follow-up): deployment-vercel.mdx MSW-mode how-to section + its
checklist/comparison entries, and implementation-status.mdx QA table column.

-### Option A: Next.js + `@objectstack/nextjs`
-
-This is the recommended approach for Vercel. The `@objectstack/nextjs` adapter maps all ObjectStack protocol endpoints to a single Next.js catch-all route.
-
-**1. Create the kernel singleton:**
-
-```typescript
-// lib/kernel.ts
-import { ObjectKernel, DriverPlugin, AppPlugin } from '@objectstack/runtime';
-import { ObjectQLPlugin } from '@objectstack/objectql';
-import appConfig from '../objectstack.config';
-
-let kernel: ObjectKernel | null = null;
-
-export async function getKernel() {
-  if (kernel) return kernel;
-
-  kernel = new ObjectKernel();
-  await kernel.use(new ObjectQLPlugin());
-
-  // Use your production driver (Postgres, MongoDB, etc.)
-  // await kernel.use(new DriverPlugin(new PostgresDriver({
-  //   url: process.env.DATABASE_URL,
-  // })));
-
-  // Load the application configuration (objects, data, etc.)
-  await kernel.use(new AppPlugin(appConfig));
-
-  await kernel.bootstrap();
-  return kernel;
-}
-```
-
-**2. Create the API route handler:**
-
-```typescript
-// app/api/[...objectstack]/route.ts
-import { createRouteHandler } from '@objectstack/nextjs';
-import { getKernel } from '@/lib/kernel';
-
-async function handler(...args: any[]) {
-  const kernel = await getKernel();
-  const routeHandler = createRouteHandler({ kernel, prefix: '/api' });
-  return routeHandler(...args);
-}
-
-export { handler as GET, handler as POST, handler as PATCH, handler as DELETE };
-```
-
-**3. `vercel.json` (optional — Next.js works out of the box):**
-
-```json
-{
-  "$schema": "https://openapi.vercel.sh/vercel.json",
-  "framework": "nextjs"
-}
-```
-
-### Option B: Hono + `@objectstack/hono` (Vite SPA)
+### Hono serverless function (`@objectstack/hono`)
 
 This is a valid self-contained pattern when you want to ship a Vite SPA *and* its API from a single Vercel project: the SPA is served as static assets, and a Hono-based serverless function handles `/api/*` requests.
