Inference engine shrunk to 1023 bytes, still runs SmolLM2-135M

utsavkhairnar previously squeezed an inference engine down to 2.9 KB—smaller than a C hello world (67,608 bytes) and small enough to fit in a QR code—running a real SmolLM2-135M model with no Python, no libraries, not even libc. A day later, cneuralnetwork pushed it under 1 KB (1,023 bytes), with a screenshot showing the engine completing a Python-style Fibonacci function. A PR is open.
