docs: make example-page Workflows notices firm and dated

The example-specific line read as a soft suggestion ("This example uses
Workflows. For new builds, use...") with no deadline. Reword it on all six
example pages to state plainly that the example stops working after the
August 18, 2026 retirement date and to migrate before then, keeping each
page's specific Assistant/Squad replacement link.
