"""Copilot module — conversational AI agent over DentalPin (issue #81).

A thin *surface* over the core agentic engine (``app/core/agents`` +
``app/core/llm``). Consumes tools through the global registry only;
never imports another module's service, so it keeps ``depends = []`` and
stays cleanly removable. Per-user RBAC parity: the agent can never see
or do anything the calling user couldn't through the UI.
