vLLM 0.9.0

First release built with the default CUDA_VERSION bumped to 12.8.1 (from 12.4.1 in v0.8.5) per docker/Dockerfile's ARG CUDA_VERSION at this tag -- as with every entry in this collection, this is vLLM's own default build target, not an exhaustive compatibility list; the wheel auto-detects the installed CUDA rather than pinning to one version.
