// @anthropic-ai/model-provider
// Model provider abstraction layer for Claude Code
//
// This package owns the model calling logic and provides:
// - Core query functions (queryModelWithStreaming, etc.)
// - Provider implementations (Anthropic, OpenAI, Gemini, Grok)
// - Type definitions (Message, Tool, Usage, etc.)
// - Dependency injection hooks (analytics, cost tracking, etc.)
//
// Initialization:
//   registerClientFactories({ ... })  // inject auth clients
//   registerHooks({ ... })            // inject analytics/cost/logging

// Hooks (dependency injection)
