feat(persistence): P6b — câblage live du checkpoint conversationnel (best-effort)

ask_agent persiste désormais chaque paire dans son conversationId : tour Prompt
à l'enqueue, tour Response au succès — best-effort (un échec de persistance ne
dégrade jamais la délégation).

- application : port RecordTurnProvider (matérialise un RecordTurn sur le bon
  project root — OrchestratorService est mono-instance multi-projets, le log est
  par root) ; wither with_record_turn(provider, Clock) ; helper
  record_turn_best_effort ; horodatage via domain::ports::Clock (pas d'horloge
  infra dans application)
- app-tauri : AppRecordTurnProvider (Fs* sur le root du projet) câblé au
  composition root avec le SystemClock partagé
- tests : 5 cas (paire Prompt→Response, fil A↔B vs User↔B, no-op sans provider,
  ask Ok même si record échoue) ; orchestrator_service 40, application +
  app-tauri verts

// ---------------------------------------------------------------------------
// P6b — live wiring of `RecordTurn` in `ask_agent` (conversation persistence).
//
// On a successful inter-agent delegation, `ask_agent` persists the **pair**
// best-effort: a `Prompt` turn at enqueue (text = task, source = requester) and a
// `Response` turn on the `Ok(Ok(result))` branch (text = result, source = target),
// both on the SAME resolved `conversation_id`. Persistence is best-effort: a missing
// provider/clock, a provider returning `None`, or a failing append must NEVER turn a
// successful ask into an error.
//
// These tests reuse the full `ask`/`reply` rendezvous harness above (real mailbox +
// mediated PTY delivery + conversation registry) and add a recording in-memory
// `ConversationLog` / `RecordTurnProvider` / fixed `Clock`, mirroring the P6a fakes
// in `conversation_record.rs`.
