feat: Phase 10 — Service Windows NSSM + cross-compilation Windows

Phase 10 (service.rs):
- install: télécharge NSSM, installe le service 'ImagodWeb' (auto-start, restart on crash)
- uninstall: arrête et supprime le service
- Service configuré avec: démarrage auto, redémarrage sur crash, délai 5s
- Extraction ZIP NSSM intégrée (crate zip, deflate only)

Phase 12 (cross-compilation Windows):
- Cible x86_64-pc-windows-gnu configurée
- Linker mingw-w64
- Corrections compatibilité: Cow→Vec dans clipboard.rs, API zip v2
- Binaire Windows .exe généré (8.1 MB, statique)

Fix: compilation croisée Windows fonctionnelle
