The workflow asset previously persisted the same value (#00ff00) as the
declared default, so the restore-from-workflow test would pass even if
load regressed and the widget silently fell back to the default. Use a
distinct persisted value (#ff00ff) so the test actually exercises
deserialization.
Tighten the AGENTS.md DevTools guidance to recommend the searchBox-based
add flow over programmatic nodeOps.addNode for tests where adding is
itself the behaviour under test.
