v0.3.0

Added

• Server-tool card labels via the catalog endpoint. get_urls() now also
  mounts django-ag-ui's tool catalog at <prefix>agent/tools/ (named
  django_admin_agent_tools), and the sidebar passes it to the Web Component as
  data-tools-url. The labels live on each tool's @tool(summary=…) (e.g.
  query_model → "Query records", inspect_modeladmin → "Inspect admin") — a
  single server-side source, fetched by the component.

Changed

• Vendored bundle → @artooi/ag-ui-web-component 0.3.0 (data-tools-url
  catalog fetch). Pins django-ag-ui>=0.3 (the catalog endpoint / ToolsView)
  and djangorestframework-mcp-server>=0.6.1.

Removed

• The static DJANGO_ADMIN_AGENT["TOOL_SUMMARIES"] setting + build_tool_summaries
  map + the embedded tool-summaries json_script — superseded by the fetched
  catalog (no per-tool client duplication). Labels now live on @tool(summary=…).
