Low Risk
Data-only catalog addition with no logic or runtime behavior changes.

Overview
Adds RTX 3500 Ada Mobile to NVIDIA_SKUS in hardware-nvidia.ts, slotted with the other Ada Lovelace workstation/mobile SKUs between RTX 4000 SFF Ada and RTX 2000 Ada.

The new entry records 15.8 TFLOPS, 12 GB VRAM, compute capability 8.9, 150 W TDP, $1,500 MSRP, and 2023 release year so task/hardware logic can recognize this laptop GPU alongside existing mobile Ada specs.
