Instead of creating new OpenRouterModelRegistry instances multiple times
per tool (4x per tool during schema generation), we now use a shared
class-level cache in BaseTool. This reduces registry loading from 40+ times
to just once during MCP server initialization.
The optimization:
- Adds _openrouter_registry_cache as a class variable in BaseTool
- Implements _get_openrouter_registry() classmethod for lazy loading
- Ensures cache is shared across all tool subclasses
- Maintains identical functionality with improved performance
This significantly reduces startup time and resource usage when OpenRouter
is configured, especially noticeable with many custom models.
