Move torch and sentence-transformers to requirements-reranker.txt so the main Docker build succeeds even if these large packages fail to install. The reranker code already handles missing imports gracefully when RERANK_ENABLED=false (the default). This fixes the production deployment — builds were failing because of the ~800MB torch dependency, preventing ALL new code from deploying. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
