testing library

Test doubles for code built on agentic_llm.

Kept in a separate entry point so production builds never carry test scaffolding, while applications and third-party plugins test against the same doubles the framework uses on itself.

import 'package:agentic_llm/testing.dart';

final model = FakeChatModel.toolCall(
  toolCalls: [ToolCallPart(id: 'c1', name: 'search_web', arguments: {'query': 'dart'})],
  then: 'Dart 3 added records and patterns.',
);

await agent.run('What is new in Dart 3?');
expect(model.callCount, 2);
