Datasette Agent can now invisibly test apps via sandboxed iframe JavaScript execution

Datasette Apps 0.2a0 adds two agent-facing tools: app_debug(), which lets an AI agent smoke-test apps by running JavaScript in a hidden iframe, and app_list(), which lets agents discover editable apps. The browser_task() mechanism enabling this headless testing is a niche but clever pattern for agentic UI validation. Primarily relevant to the Datasette/Simon Willison ecosystem rather than the broader AI conference circuit.
