feat(*): add staged curriculum training with an automated stage-by-stage orchestrator

training/curriculum.sh

+#!/usr/bin/env bash
+# Runs the staged curriculum (see TRAINING.md, curriculum.py) detached from
+# your SSH session, the same way start_training.sh does for a single run —
+# safe to disconnect any time. Uses its own tmux session ("cosmic-curriculum")
+# so it doesn't collide with a manual next_run.sh/start_training.sh run.
+#
+# Usage: ./curriculum.sh [curriculum.py args...]
+# e.g.:  ./curriculum.sh
+#        ./curriculum.sh --seed-checkpoint checkpoints/run11/final.zip
+#        ./curriculum.sh --force-retry
