The Streamable HTTP example in packages/middleware/hono/README.md does not compile under strict TypeScript. This adds the Context annotation that docs/serving/hono.md already uses.

Motivation and Context

createMcpHonoApp() returns a plain Hono (packages/middleware/hono/src/hono.ts:83). With an inferred callback context, c.get's key parameter narrows to never, so the README's c.get('parsedBody') fails:

error TS2769: No overload matches this call.
  Overload 1 of 2, '(key: never): unknown', gave the following error.
    Argument of type '"parsedBody"' is not assignable to parameter of type 'never'.

docs/serving/hono.md:29 uses (c: Context) => and its tip at line 37 explains the same failure. The README example now matches:

 import { createMcpHonoApp } from '@modelcontextprotocol/hono';
+import type { Context } from 'hono';

 const app = createMcpHonoApp();
-app.all('/mcp', async c => {
+app.all('/mcp', async (c: Context) => {

import type { Context } from 'hono' is the same import docs/serving/hono.md:17 and src/hono.ts:2 use.

How Has This Been Tested?

The example's route callback was compiled before and after with tsc --noEmit --strict (TypeScript 5.9.3, Hono 4.12.9 as pinned in pnpm-lock.yaml), with createMcpHonoApp declared with its real Hono return type and the transport stubbed: TS2769 before (exit 2), clean after (exit 0). That was a focused type check, not a full app build.
