Full rewrite of EN/ZH/JA as a progressive essay with harness-essay spine,
six-pattern toolbox, neighbor comparisons, and SVG-first figures

longest-prefix resume in the teaching runtime; bump translation-sync to v15.

Introduce Classify-And-Act through Loop Until Done after primitives,
map each onto agent/parallel/pipeline, show review-changes as a
fanout+verify composition, and add a matching six-panel SVG.
