fix: revue complète obsigate-desktop — 6 correctifs pour le prochain build

1. main.rs: .current_dir(exe_dir) pour que Python trouve backend/ (pas le cwd hérité)
2. build-windows.bat: dir bundles pointe vers target/x86_64-.../release (était target/release)
3. build-windows.bat: supprimer étape 3 inutile (frontend-static) — Tauri utilise ../frontend
4. capabilities/default.json: requis par Tauri v2 (permissions plugins)
5. tauri.conf.json + Cargo.toml: retirer updater (placeholder sans clé)
6. .gitignore: ajouter desktop/target/, python-embed/, frontend-static/
7. build-linux.sh: mêmes corrections (bundles path, simplification)

desktop/build-windows.bat
