Remove AMD ROCm support — CPU and NVIDIA only

BREAKING: Remove Dockerfile.rocm, compose.rocm.yaml, and ROCm image build/push from the release pipeline. Remove AMD quick-start and ROCm references from README and DEVELOPER docs. Update docker-deployment and developer-docs specs to reflect CPU + NVIDIA only. The ROCm variant added significant complexity (4.2GB torch wheel, >20GB container) with limited usage. Users on AMD GPUs should stay on engine v3.2.x or switch to CPU mode. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
