v0.1.0

Added

• Chat-agent sidebar for the Django admin, built on django-ag-ui and the
  vendored @artooi/ag-ui-web-component <ag-ui-chat> bundle.
• Default server-side tool registry (build_default_registry) of read-only
  shell.* (query / count / fetch / inspect-schema) and introspect.*
  (model + admin registration) tools, plus register_*_tools builders and
  get_urls() to mount the agent endpoint.
• Frontend admin tool layer: nav.* navigation and DOM-driving handlers
  (fill field, click, apply changelist filter) with visible animations, and a
  confirmation modal gating x-destructive tools.
• Sidebar wiring: the {% django_admin_agent_sidebar %} template tag and a
  SidebarAdminSite (each_context) path, with an admin route + page map.
• Django Unfold compatibility shim (runtime JS; lazy, guarded Python).
• Optional [mcp] extra exposing the admin tools as an HTTP MCP server via
  djangorestframework-mcp-server.
