     * HuggingFace Tool Calling Support (Enhanced 2025)

     * **Supported Models (Tool Calling Enabled):**
     * - meta-llama/Llama-3.1-8B-Instruct - Post-trained for tool calling
     * - meta-llama/Llama-3.1-70B-Instruct - Advanced tool calling capabilities
     * - meta-llama/Llama-3.1-405B-Instruct - Full tool calling support
     * - nvidia/Llama-3.1-Nemotron-Ultra-253B-v1 - Optimized for tool calling
     * - NousResearch/Hermes-3-Llama-3.2-3B - Function calling trained
     * - codellama/CodeLlama-34b-Instruct-hf - Code-focused tool calling
     * - mistralai/Mistral-7B-Instruct-v0.3 - Basic tool support
     *
     * **Unsupported Models (Tool Calling Disabled):**
     * - microsoft/DialoGPT-* - Treats tools as conversation context
     * - gpt2, bert, roberta variants - No tool calling training
     * - Most pre-2024 models - Limited function calling capabilities
     *
     * **Implementation Details:**
     * - Intelligent model detection based on known capabilities
     * - Custom tool schema formatting for HuggingFace models
     * - Enhanced response parsing for function call extraction
     * - Graceful fallback for unsupported models
     *
     * @returns true for supported models, false for unsupported models
