feat: PyTorch vs Aether side-by-side inference

Left column: base SmolLM2-360M on PyTorch CPU (the standard)
Right column: Buleyean SmolLM2-360M on Aether (our engine)

Aether runs the entire inference pipeline in pure TypeScript + JS:
GGUF parse -> dequant -> matVec -> RoPE -> SwiGLU -> sampling
Zero external ML dependencies. Shows timing for both.

Docker SDK with Python 3.11 + Node.js 20.
