feat: v0.7.0 — am run/start --provider/--model : résolution cloud via le registre (base_url + keyring + modèle), fallback cloud quand le modèle local est inconnu, canal model_env/model_arg/env_map, jamais de token en clair (closes #92)

- apply_provider : providers::resolve_for (flag > agent > défaut) + apply_env_map_resolved (api_key = @secret, base_url/model du provider résolu)
- start/run/restart : --provider et --model dans le CLI, le REPL et la complétion ; specs help + man pages
- Tests unitaires : résolution, cascade, canal déclaré, erreur provider inconnu (liste), absence de fuite (env sans valeur sk-), fallback embarqué
