Insère automatiquement les schémas dans les supports ; module 3 illustré
inserer.py ajoute chaque figure (SVG + repli PNG) après l'introduction de sa section, avec une légende numérotée. Il est idempotent (les cadres schema-* sont retirés puis réinsérés) et garde mimetype en tête du zip. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
