Adds use-multi-head-policy workflow parameter (default "0") wired into the container env block as FOXHUNT_USE_MULTI_HEAD_POLICY. Adds --use-multi-head-policy flag to argo-alpha-rl.sh that passes through to the workflow. Enables Phase 2A-E cluster verification with the multi-head policy mixture (commits0b3e40150→c8c81ab7e). Without this flag, the cluster runs the legacy single-head path identical to pre-Phase-2A behavior. Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
