Fix #5: accumulate Task 2 classification credit into final score — action scaled to 0.7 max, classify adds up to 0.3, total 1.0

Fix #4: use resolution_hint in reply scoring — category hits 0.03, hint hits 0.05, cap 0.25 (intentional specificity incentive)

Fix #3: track _classified_correctly separately — wrong classification no longer gets free 0.20 credit in Task 3; TODO comment added to Task 2 classify branch
