qualite(P1): activer ruff/mypy progressifs et corriger le scope cible

- Ajoute un job typecheck progressif dans la CI et restreint lint/format au perimetre stabilise pour obtenir des gates fiables.

- Corrige les points bloquants du scope cible (import sys manquant, signatures Optional, hygiene format/ruff).

- Aligne les tests et TODO sur l'etat reel de la phase P1 (ruff/mypy actives en progressif).
