Aspire 13.2 renamed the hosting integration from Aspire.Hosting.Azure.AIFoundry to Aspire.Hosting.Foundry, including namespace and related type renames. This update ensures the 13.2 changelog explicitly documents the full migration surface and removes stale legacy identifiers from docs content.

• 13.2 changelog: complete migration mapping

  • Expanded the breaking-changes entry in whats-new/aspire-13-2.mdx with a full rename table (package, namespace, and type renames).
  • Added a concise migration tip covering package reference, using directive, and direct type-reference updates.
  • Updated section naming and intra-page links to match the new transition section title.

• Legacy-name cleanup in docs content

  • Removed remaining legacy AIFoundry/AddAzureAIFoundry mentions under src/frontend/src/content/docs/.
  • Updated Foundry migration examples to use current APIs (AddFoundry, FoundryModel) and current naming guidance.
  • Applied equivalent cleanup in localized 13.2 release notes (ja/whats-new/aspire-13-2.mdx) for consistency.

• Related integration guidance alignment

  • Revised the upgrade note in azure-ai-foundry-host.mdx to describe migration using current Foundry naming without retaining deprecated identifiers.
