* HuggingFace models currently don't properly support tool/function calling

* **Tested Models & Issues:**
* - microsoft/DialoGPT-medium: Describes tools instead of executing them
* - Most HF models via router endpoint: Function schema passed but not executed
* - Issue: Models treat tool definitions as conversation context rather than executable functions
*
* **Known Limitations:**
* - Tools are visible to model but treated as descriptive text
* - No proper function call response format handling
* - HuggingFace router endpoint doesn't enforce OpenAI-compatible tool execution
*
* @returns false to disable tools by default until proper implementation
