datasette-apps 0.3a0

Summary

datasette-apps 0.3a0 adds support for hosting and editing custom HTML applications inside Datasette, and improves their integration with Datasette Agent. Users can tag apps in agent chat by typing #, and new app_add_stored_queries() and app_remove_stored_queries() tools let the agent manage which stored queries an app may call. Granting a write query requires the user's approval, and app_create() checks that each requested stored query exists and is viewable by the user.
