Breaking Changes

• fix(mcp-apps)!: give MCP App widgets an opaque origin by default (#7896) (b0c1736)
  MCP App widgets now run in a sandbox without
  allow-same-origin, so they get an opaque origin and cannot use
  localStorage, sessionStorage, IndexedDB or cookies.
  Requests from a widget that need CORS, such as module scripts and fetch,
  are now sent with Origin: null. Serve public widget assets with
• fix(a2ui-renderer)!: type createCatalog renderer props as the binder resolves them (#7815) (0ea6f28)
  createCatalog renderers (and the deprecated
  createA2UICatalog render) now get props typed as the A2UI binder
  resolves them, so code written against the raw schema types can stop
  compiling.
  Call Action props as functions, for example props.onPress(), instead
  of reading them as action objects.
  Use bound props as plain values (props.level is a number) and drop
  handling of the { path } and { call } shapes, which renderers never
  receive at runtime.
  A plain z.array(z.string()) prop now resolves to any like a child
  list, so annotate callback parameters, for example
  props.children.map((id: string) => …).
