Bootstrap a modular AI agent with OpenRouter SDK, extensible hooks, and optional terminal UI.

• Standalone agent core runs independently of any UI, with event-based hooks for streaming responses, tool calls, reasoning, and errors
• Items-based streaming model emits complete, progressively updated items by ID rather than accumulating chunks, enabling efficient React state management and concurrent output handling
• Supports 300+ language models via OpenRouter with dynamic model discovery; use openrouter/auto for automatic selection or query the models API by author, context length, and pricing
• Optional Ink TUI provides a beautiful terminal interface; agent also works headless for HTTP APIs, Discord bots, or programmatic use
• Built-in tool system with Zod schemas; add tools at runtime or define custom ones for calculator, time, web search, file operations, and image generation
