OpenHands QA loop — demo artifacts (v2)

Artifacts produced by OpenHands authoring the four policies scenarios and the Duplicate row action on this branch. The mp4 is the slow-mo recording (E2E_FILM=1, 400 ms per Playwright action) of the policies-duplicate scenario exercising the Duplicate feature end to end. The trace.zip loads into https://trace.playwright.dev for the time-travel DOM + network viewer.
