Datasette Apps 0.2a0 Adds Improved Debugging Capabilities

Datasette Apps version 0.2a0 introduces improvements designed for building and editing applications through the Datasette Agent. The new app_debug() tool stands out, operating through an invisible iframe (with opacity: 0 and pointer-events: none) where the agent can execute JavaScript code in a sandboxed environment. The feature enables the agent to perform validation tests on the application, including measuring interface element dimensions. It leverages the new context.browser_task() mechanism introduced in Datasette Agent 0.4a0.
