Clarify TanStack AI durability setup

[tannerlinsley]

Evidence

Follow-up to #1174. The RC announcement described durability as middleware passed to chat(), but the authoritative TanStack AI resumable-stream docs configure durability as an adapter on the streaming response.

Change

Keep the middleware examples intact and state the separate durability integration point.

Impact

Prevents readers from trying to configure resumable delivery through the wrong API.

Validation

• pnpm test passed before commit and again in the commit hook: TypeScript and type-aware lint clean; 366 tests passed, 1 environment-gated docs smoke test skipped
• All 25 TanStack AI documentation links in the announcement return HTTP 200
• git diff --check passed

Risk

Low. One copy-only sentence changes; no runtime or API behavior changes.

Summary by CodeRabbit

• Documentation
  • Clarified that durability integrates with streaming responses through an adapter, rather than being passed directly as middleware to chat().
