feat(agent): wire auto-review (review_enabled no-op -> nyata)

review_enabled (default TRUE) selama ini no-op: tampil di TUI settings
overlay ("Review: true"), bisa di-toggle via command, TAPI spawn_background_review
tidak pernah dipanggil & Origin::Reviewer tidak pernah dikonstruksi. User
melihat "Review: true" padahal auto-review setelah edit tak pernah jalan.

Sekarang feature yang sudah dibangun penuh (subagent/auto/engine.rs: git diff
-> LLM review -> auto-fix HIGH/MEDIUM) di-wire:
- daemon/handler.rs: trigger setelah run_turn bila review_enabled; capture
  flag+creds SEBELUM api_key/provider_cfg di-move ke LlmClient.
- tui/turn.rs: sama, gated by state.settings.flags.review_enabled.
- ws/lib.rs: channel minimal tanpa settings -> review nyala tiap prompt
  (konsisten dgn default ON).

Aman: review fire-and-forget (tokio::spawn), get_git_diff skip bila no-change,
no-op bila bukan git repo (auto/engine). Creds dipakai = creds ter-resolve yg
sama dgn komposisi turn.

Verifikasi: check/clippy/fmt/test workspace hijau (0 error/warning/fail).
