Re-ran stage-3 (curric-s3-no_draws vs curric-s2-defend) and the missing stage-4 gate now that the locomotion-mask inference bugfix is in. Both reverse or contradict the pre-fix bookkeeping: curric-s2-defend (grounded) beats curric-s3-no_draws 60-26 and curric-s4-mechanics 57-24 when fairly evaluated, so lifting the locomotion mask in stage 3 was a real regression in floor play, not the improvement the buggy eval reported. Adds a stage-5 "aggression" curriculum entry that resumes from stage 2 directly (via new resume_from_experiment/reference_experiment stage-dict overrides in curriculum.py) instead of compounding the regression through stages 3-4, keeps the locomotion mask on, and retunes ball-pursuit reward weights for much more aggressive floor play. Extends train.py with the three new --velocity-to-ball-weight/--ball-distance-penalty/--ball-touch-reward flags needed to forward that retune to Godot's existing SHIP_AI_OVERRIDES. curriculum_state.json and TRAINING.md are corrected/annotated in place rather than silently rewritten, so the regression stays visible in history.
