13.4 upgrade notes

Aspire.Hosting.Netlify is now built against Aspire 13.4.0.

What changed

All first-party Aspire package pins and sample AppHost SDK versions are updated to 13.4.0.
The JavaScript community toolkit used by the samples is updated to 13.4.0.
The Aspire integration analyzer is enabled with EnableAspireIntegrationAnalyzers, so exported ATS surfaces are validated at build time.
[AspireExport(Description = ...)] usage has been removed in favor of XML doc comments, which flow into generated TypeScript SDK docs.
The TypeScript quickstart sample now uses the Aspire 13.4 AppHost layout: apphost.mts, tsconfig.apphost.json, and generated SDK files under .aspire/modules/.

Existing pre-13.4 TypeScript AppHosts that use apphost.ts and .modules/ continue to work, but new projects should use the 13.4 layout:

import { Aspire } from "./.modules/aspire";
import { createBuilder } from "./.aspire/modules/aspire.mjs";

Update aspire.config.json to point at apphost.mts, regenerate with aspire restore, then run your TypeScript build.
