PufferLib

Use PufferLib with an explicit version profile. Upstream currently has two incompatible surfaces:

Profile Status on 2026-07-23 Main use
pufferlib==3.0.0 Latest stable PyPI release, published 2025-06-23 Python/Gymnasium/PettingZoo emulation, pufferlib.vector, Torch PuffeRL
source 4.0 Upstream default branch; not the latest stable PyPI artifact Native C Ocean environments, native CUDA trainer, optional Torch fallback

Do not combine 3.0 imports with 4.0 config/CLI examples. The 4.0 redesign removed the 3.0 emulation, vector, and pytorch modules from the current package tree.
