chore(typo): retire tous les tirets cadratins/demi-cadratins + garde CI

Remplace les 547 tirets cadratins (U+2014) et demi-cadratins (U+2013) des fichiers versionnés par la ponctuation contextuelle adaptée (point médian, deux-points, virgule, parenthèses ; tiret simple pour les plages), sur 122 fichiers (appli, vitrine, doc, tests, workflows, scripts).

Ajoute le job CI « lint-dashes » (git grep -P) qui échoue si un tiret cadratin/demi-cadratin réapparaît, hors logo binaire et captures brutes du terminal (fidélité des fixtures de détection de dialogue).
