            Full-featured LLM inference engine for ESP32 microcontrollers.

            ### Features
            - INT8/Binary quantized inference (~20KB RAM)
            - Product quantization (8-32x compression)
            - MicroLoRA on-device adaptation
            - HNSW vector search (1000+ vectors)
            - Semantic memory with RAG
            - Multi-chip federation (pipeline/tensor parallel)
            - Speculative decoding (2-4x speedup)
            - Anomaly detection

            ### Installation
