v0.5.11

Added

• Multi-GPU simulation for repeated --gpu flags, comma-separated GPU specs, and count shorthand like 2x RTX 4090.
• python -m whichllm now runs the CLI.
• --gpu-only and --fit full-gpu filter recommendations to models that fit fully in GPU VRAM.
• T5 lineage support for version-aware benchmark handling.

Fixed

• Cached model and benchmark data are read as UTF-8.
• GTX 1650 simulation distinguishes GDDR5 and GDDR6 variants by memory clock.
• RAM reserve logic now uses a bounded reserve formula instead of a fixed 80% usable-RAM cap.
