Preserve native Codex history and add configurable cross-model compression

Separate encrypted reasoning from actual compaction, stop migration after native return, and retain full history and recent exchanges. Add typed settings, Gemini fallback, verified provider windows, bounded summaries and durable concurrent checkpoints.

Validation: 245 bridge tests plus focused concurrency tests; 71 settings/connection tests; 66 supplementary tests; TypeScript checks; renderer and Electron bundles; real primary/native/fallback summary probes and 700K input acceptance.

 ## Veri ve güncellemeler
 
+### Codex bağlam ve sıkıştırma
+
+Codex Bağlama ayarları, ek model içeren geçişlerde sıkıştırıcı/yedek model,
+ayrıntı seviyesi, korunacak mesajlaşmalar, yüzde/token bütçesi ve otomatik eşik
+seçimini sunar. Varsayılanlar: Gemini 3.8 Flash High, yedek Gemini 3 Flash,
+10 mesajlaşma, geçişte %70, otomatik tetiklemede %70 ve sonrasında %50.
+Kapasite bağlantıdan gelen model bilgisiyle hesaplanır; 272K genel tavan yoktur.
+Girdi hesabı talimatlar ve araçları da içeren temkinli bir token tahminidir.
+
+Abonelik modellerinin kendi aralarındaki istekler ve GPT-Live ses yolu özgün
+Codex hattında kalır. Şifreli reasoning yalnız ek model için hazırlanan kopyada
+görünür metnine indirgenir; gerçek şifreli konuşma özeti sahibi tarafından açılır.
+Sohbet kimliği ve özgün konuşma kaydı değiştirilmez. Doğrulanmış özet sürümleri
+köprü veri dizinindeki `compression-checkpoints.sqlite3` içinde saklanır.
+Son mesajlaşmalar bütçeye sığmıyorsa sayı kendiliğinden azaltılmaz.
+
 Windows ajan verisi `%LOCALAPPDATA%/TurkServis/AITURK-IDE/agent` altında tutulur.
 `AITURK_IDE_HOME` açıkça başka bir konum seçmek için kullanılabilir.
 Mevcut Hermes kurulumu ve `HERMES_HOME` dizini otomatik olarak devralınmaz.
