feat(agent): routage LaunchAgent structuré vs PTY + réconciliation A/B (D3) — §17

- LaunchAgent route sur profile.structured_adapter : Some ⇒ AgentSession via
  factory + enregistrement StructuredSessions (aucun pty.spawn) ; None ⇒ PTY
  inchangé. Dépendances structurées injectées par builders additifs
  with_structured (signatures publiques inchangées ⇒ A/B legacy verts).
- LaunchAgentOutput étendu d'un champ optionnel structured (non cassant).
- A (ChangeAgentProfile) : kill polymorphe — session structurée ⇒ shutdown(),
  PTY ⇒ kill ; détection sur les deux registres.
- B : resume_supported vrai pour profil structuré ; resolve_session_plan ⇒
  Resume{conversation_id} (Claude --resume / Codex exec resume).
- Codex : build_spawn_line porte --sandbox workspace-write --ask-for-approval
  never (autonomie d'écriture ; à terme piloté par les permissions).

Tests : structured_launch 8 + codex flags 2 ; application/infrastructure 0 échec.

Reste D4 : ChatBridge (Channel) + commandes agent_send/reattach + StructuredSessions
dans AppState + DTO cellKind/ReplyChunk.
