Nodrix build assistant — LoRA adapter (v2-qwen7b)

LoRA adapter fine-tuning Qwen/Qwen2.5-Coder-7B-Instruct into an assistant for the Nodrix ESP32/Arduino library. Trained in Unsloth Studio (MLX, Apple Silicon). LoRA r=16, alpha=16, all linear modules, seq 512, 3 epochs / 69 steps, 183 training examples.

Added 20 downlink examples. Fixed setCACert but overfit past ~step 24 (eval floor ~2.04). Superseded by v3.
