chore: bump version to 0.2.2

Ships the AYM/Uyuşmazlık API migration (fadc3b0), which landed after the
v0.2.1 release and so never reached PyPI. Fixes #33.

+## 🚀 5 Dakikada Başla (Remote MCP)
+
+### ✅ Kurulum Gerektirmez! Hemen Kullan!
+
+🔗 **Remote MCP Adresi:** `https://yargimcp.surucu.dev/mcp`
+
+> ⚠️ **Eski adres** `https://yargimcp.fastmcp.app/mcp` **artık kullanım dışıdır** — yalnızca taşındığını bildiren bir uyarı tool'u döner. Lütfen yukarıdaki yeni adresi kullanın.
+
+### Claude Desktop ile Kullanım (Ücretli abonelik gerekir)
+
+1. **Claude Desktop'ı açın**
+2. **Settings → Connectors → Add Custom Connector**
+3. **Bilgileri girin:**
+   - **Name:** `Yargı MCP`
+   - **URL:** `https://yargimcp.surucu.dev/mcp`
+4. **Add** butonuna tıklayın
+5. **Hemen kullanmaya başlayın!** 🎉
+
+### Google Antigravity ile Kullanım (Lokal `uv` Kurulumu — Kopyala-Yapıştır)
+
+> **Ön Gereksinimler:** Bilgisayarınızda **Python**, **`uv`** ([kurulum](https://docs.astral.sh/uv/getting-started/installation/)) ve **Node.js** ([indir](https://nodejs.org/en/download)) kurulu olmalı. (Node.js yalnızca aşağıdaki kurulum komutunu çalıştırmak için gerekir; MCP'yi `uvx` çalıştırır.)
+
+Aşağıdaki **bloğun tamamını** terminale yapıştırın. Komut, Antigravity'nin okuduğu `~/.gemini/config/mcp_config.json` dosyasını sizin yerinize oluşturur/günceller (varsa diğer sunucularınız korunur):
+
+**macOS / Linux** (Terminal):
+
+```bash
+node - <<'YARGI'
+const fs=require("fs"),os=require("os"),path=require("path");
+const dir=path.join(os.homedir(),".gemini","config"),file=path.join(dir,"mcp_config.json");
+fs.mkdirSync(dir,{recursive:true});
+let cfg={};try{cfg=JSON.parse(fs.readFileSync(file,"utf8"))}catch{}
+if(typeof cfg!=="object"||cfg===null||Array.isArray(cfg))cfg={};
+if(typeof cfg.mcpServers!=="object"||cfg.mcpServers===null)cfg.mcpServers={};
+cfg.mcpServers["yargi-mcp"]={command:"uvx",args:["yargi-mcp"]};
+fs.writeFileSync(file,JSON.stringify(cfg,null,2)+"\n");
+console.log("yargi-mcp eklendi -> "+file);
+YARGI
+```
+
+**Windows** (PowerShell):
+
+```powershell
+@'
+const fs=require("fs"),os=require("os"),path=require("path");
+const dir=path.join(os.homedir(),".gemini","config"),file=path.join(dir,"mcp_config.json");

+cfg.mcpServers["yargi-mcp"]={command:"uvx",args:["yargi-mcp"]};
+fs.writeFileSync(file,JSON.stringify(cfg,null,2)+"\n");
+console.log("yargi-mcp eklendi -> "+file);
+'@ | node -
+```
+
+Komut `yargi-mcp eklendi -> ...` çıktısını verdiğinde kurulum tamamlanmıştır. Antigravity'yi (açıksa kapatıp) yeniden başlatın; `yargi-mcp` araçları otomatik yüklenir.
+
+> 💡 **İpucu:** Lokal kurulumda hukuk kaynaklarına erişim doğrudan bilgisayarınızda `uvx yargi-mcp` ile çalışır; uzaktan sunucuya ihtiyaç duymaz.
+
+### Remote MCP Sorun Giderme
+
+`https://yargimcp.surucu.dev/mcp` bir web sayfası değil, Streamable HTTP MCP uç noktasıdır. Tarayıcıda açınca veya düz `curl` ile GET isteği atınca `406 Not Acceptable` ve `Client must accept text/event-stream` benzeri bir yanıt görmek normaldir; bu, sunucunun kapalı olduğu anlamına gelmez. MCP istemcisi `Accept: application/json, text/event-stream` başlığıyla JSON-RPC isteği göndermelidir.
+
+Hızlı sağlık kontrolü için tarayıcıda şu adresleri açabilirsiniz:
+
+- `https://yargimcp.surucu.dev/health` — servis sağlık durumu
+
+Claude.ai veya başka bir istemci "araç yok" gibi davranırsa:
+
+1. Connector'ı kaldırıp yeniden ekleyin.
+2. URL olarak önce `https://yargimcp.surucu.dev/mcp` deneyin; istemciniz yönlendirmeleri takip etmiyorsa `https://yargimcp.surucu.dev/mcp/` deneyin.
+3. Eski `https://yargimcp.fastmcp.app/mcp` adresinin istemci ayarlarında veya önbellekte kalmadığından emin olun.
+4. İstemcinin remote/Streamable HTTP MCP desteklediğini ve `text/event-stream` kabul ettiğini kontrol edin.

+Yargı MCP, **semantik arama** özelliği ile kararları anlamsal olarak sıralayabilir. Opsiyoneldir; iki yoldan biri yapılandırıldığında otomatik etkinleşir:
 
-### **Danıştay Araçları (Triple API + 27 Daire Filtreleme)**
-* **Ana API'lar:**
-    * `search_danistay_by_keyword(andKelimeler, orKelimeler, ...)`: Danıştay kararlarını anahtar kelimelerle arar.
-    * `search_danistay_detailed(daire, esasYil, ...)`: Danıştay kararlarını detaylı kriterlerle arar.
-    * `get_danistay_document_markdown(id: str)`: Belirli bir Danıştay kararının metnini Markdown formatında getirir.
-* **Bedesten API (Alternatif):**
-    * `search_danistay_bedesten(phrase, birimAdi, kararTarihiStart, kararTarihiEnd, ...)`: Bedesten API ile Danıştay kararlarını arar. **27 daire/kurul seçeneği** + **Tarih Filtreleme** + **Kesin Cümle Arama** (`"\"idari işlem\""`) (1-17. Daireler, Vergi/İdare Kurulları, Askeri Mahkemeler)
-    * `get_danistay_bedesten_document_markdown(documentId: str)`: Bedesten'den karar metni
+- **Yerel** (önerilen, ücretsiz): kendi makinenizdeki OpenAI-uyumlu embedding sunucusu (HuggingFace TEI, llama.cpp, Ollama, vLLM, LM Studio…)
+- **Hosted**: OpenRouter API anahtarı
 
-### **Diğer Mahkemeler (Bedesten API + Gelişmiş Arama)**
-* **Yerel Hukuk Mahkemeleri:**
-    * `search_yerel_hukuk_bedesten(phrase, kararTarihiStart, kararTarihiEnd, ...)`: Yerel hukuk mahkemesi kararlarını arar + **Tarih & Kesin Cümle Arama** (`"\"sözleşme ihlali\""`)
-    * `get_yerel_hukuk_bedesten_document_markdown(documentId: str)`: Karar metni
-* **İstinaf Hukuk Mahkemeleri:**
-    * `search_istinaf_hukuk_bedesten(phrase, kararTarihiStart, kararTarihiEnd, ...)`: İstinaf mahkemesi kararlarını arar + **Tarih & Kesin Cümle Arama** (`"\"temyiz incelemesi\""`)
-    * `get_istinaf_hukuk_bedesten_document_markdown(documentId: str)`: Karar metni
-* **Kanun Yararına Bozma (KYB):**
-    * `search_kyb_bedesten(phrase, kararTarihiStart, kararTarihiEnd, ...)`: Olağanüstü kanun yolu kararlarını arar + **Tarih & Kesin Cümle Arama** (`"\"kanun yararına bozma\""`)
-    * `get_kyb_bedesten_document_markdown(documentId: str)`: Karar metni
+### Semantik Arama Nasıl Çalışır?
+1. `initial_keyword` ile Bedesten API'den 100 karar çekilir
+2. `query` ile bu kararlar embedding modeli kullanılarak anlamsal olarak sıralanır
+3. En alakalı kararlar döndürülür
 
-* **Emsal Karar Araçları:**
-    * `search_emsal_detailed_decisions(search_query: EmsalSearchRequest) -> CompactEmsalSearchResult`: Emsal (UYAP) kararlarını detaylı kriterlerle arar.
-    * `get_emsal_document_markdown(id: str) -> EmsalDocumentMarkdown`: Belirli bir Emsal kararının metnini Markdown formatında getirir.
+### Önerilen Türkçe Kurulumu (Yerel — `multilingual-e5-large`)
 
-* **Uyuşmazlık Mahkemesi Araçları:**
-    * `search_uyusmazlik_decisions(search_params: UyusmazlikSearchRequest) -> UyusmazlikSearchResponse`: Uyuşmazlık Mahkemesi kararlarını çeşitli form kriterleriyle arar.
-    * `get_uyusmazlik_document_markdown_from_url(document_url: HttpUrl) -> UyusmazlikDocumentMarkdown`: Bir Uyuşmazlık kararını tam URL'sinden alıp Markdown formatında getirir.
+`intfloat/multilingual-e5-large` Türkçe için kıyas ettiğimiz açık kaynak modeller arasında en iyilerinden. HuggingFace'in **Text Embeddings Inference (TEI)** sunucusuyla tek komutta ayağa kalkar ve OpenAI-uyumlu API sunar:
 
-* **Anayasa Mahkemesi (Norm Denetimi) Araçları:**
-    * `search_anayasa_norm_denetimi_decisions(search_query: AnayasaNormDenetimiSearchRequest) -> AnayasaSearchResult`: AYM Norm Denetimi kararlarını kapsamlı kriterlerle arar.
-    * `get_anayasa_norm_denetimi_document_markdown(document_url: str, page_number: Optional[int] = 1) -> AnayasaDocumentMarkdown`: Belirli bir AYM Norm Denetimi kararını URL'sinden alır ve 5.000 karakterlik sayfalanmış Markdown içeriğini getirir.
+```bash
+docker run -p 8080:80 ghcr.io/huggingface/text-embeddings-inference:latest \
+    --model-id intfloat/multilingual-e5-large
+```
 
-* **Anayasa Mahkemesi (Bireysel Başvuru) Araçları:**
-    * `search_anayasa_bireysel_basvuru_report(search_query: AnayasaBireyselReportSearchRequest) -> AnayasaBireyselReportSearchResult`: AYM Bireysel Başvuru "Karar Arama Raporu" oluşturur.
-    * `get_anayasa_bireysel_basvuru_document_markdown(document_url_path: str, page_number: Optional[int] = 1) -> AnayasaBireyselBasvuruDocumentMarkdown`: Belirli bir AYM Bireysel Başvuru kararını URL path'inden alır ve 5.000 karakterlik sayfalanmış Markdown içeriğini getirir.
+Sonra Yargı MCP'ye şu env vars'ları geçirin:
 
-* **KİK (Kamu İhale Kurulu) Araçları:**
-    * `search_kik_decisions(search_query: KikSearchRequest) -> KikSearchResult`: KİK (Kamu İhale Kurulu) kararlarını arar. 
-    * `get_kik_document_markdown(karar_id: str, page_number: Optional[int] = 1) -> KikDocumentMarkdown`: Belirli bir KİK kararını, Base64 ile encode edilmiş `karar_id`'sini kullanarak alır ve 5.000 karakterlik sayfalanmış Markdown içeriğini getirir.
-* **Rekabet Kurumu Araçları:**
+```bash
+EMBEDDING_PROVIDER=local
+LOCAL_EMBEDDING_BASE_URL=http://localhost:8080/v1
+LOCAL_EMBEDDING_MODEL=intfloat/multilingual-e5-large
+LOCAL_EMBEDDING_DIMENSION=1024
+EMBEDDING_PROMPT_STYLE=e5
+```
+
+> ⚠️ **Önemli:** `EMBEDDING_PROMPT_STYLE=e5` şart — e5 modelleri `query:` / `passage:` öneki bekleyecek şekilde eğitilmiştir; yanlış önek sessizce kaliteyi düşürür.
+
+#### Claude Desktop örneği (yerel TEI)
+```json
+{
+  "mcpServers": {
+    "Yargı MCP": {
+      "command": "uvx",
+      "args": ["yargi-mcp"],
+      "env": {

+        "EMBEDDING_PROMPT_STYLE": "e5"
+      }
+    }
+  }
+}
+```
+
+### Alternatif 1: Ollama (yerel, daha hafif kurulum)
+
+```bash
+ollama serve
+ollama pull nomic-embed-text   # 768 dim, İngilizce ağırlıklı
+```
+
+```bash
+EMBEDDING_PROVIDER=local
+LOCAL_EMBEDDING_BASE_URL=http://localhost:11434/v1
+LOCAL_EMBEDDING_MODEL=nomic-embed-text
+LOCAL_EMBEDDING_DIMENSION=768
+EMBEDDING_PROMPT_STYLE=raw
+```
+
+> Ollama kütüphanesinde `multilingual-e5-large` doğrudan yok; Türkçe için TEI yolu daha doğru sonuç verir.
+
+### Alternatif 2: OpenRouter (hosted)
+
+```bash
+OPENROUTER_API_KEY=sk-or-v1-xxx...
+# İsteğe bağlı — varsayılan google/gemini-embedding-001 (3072 dim, ÜCRETLİ)
+# OPENROUTER_EMBEDDING_MODEL=...
+# OPENROUTER_EMBEDDING_DIMENSION=...
+# EMBEDDING_PROMPT_STYLE=gemini   # varsayılan
+```
+
+API anahtarınızı [openrouter.ai/keys](https://openrouter.ai/keys) adresinden alın. Varsayılan model `google/gemini-embedding-001` artık ücretli — ücretsiz bir model seçerseniz `OPENROUTER_EMBEDDING_MODEL`, `OPENROUTER_EMBEDDING_DIMENSION` ve uygun `EMBEDDING_PROMPT_STYLE` değerlerini birlikte ayarlayın.

-    targetPort: 8000
-  type: LoadBalancer
-```
-
-## Güvenlik Hususları
-
-### 1. Kimlik Doğrulama
-
-`API_TOKEN` ortam değişkenini ayarlayarak token kimlik doğrulamasını etkinleştirin:
-
-```bash
-export API_TOKEN=gizli-token-degeri
-```
-
-Ardından isteklere ekleyin:
-```bash
-curl -H "Authorization: Bearer gizli-token-degeri" http://localhost:8000/api/tools
-```
-
-### 2. HTTPS/SSL
-
-Production için her zaman HTTPS kullanın:
-
-1. SSL sertifikası edinin (Let's Encrypt vb.)
-2. Nginx veya cloud sağlayıcıda yapılandırın
-3. `ALLOWED_ORIGINS` değerini https:// kullanacak şekilde güncelleyin
-
-### 3. Rate Limiting (Hız Sınırlama)
-
-Sağlanan Nginx yapılandırması rate limiting içerir:
-- API endpoint'leri: 10 istek/saniye
-- MCP endpoint: 100 istek/saniye
-
-### 4. CORS Yapılandırması
-
-Production için belirli kaynaklara izin verin:
-
-```bash
-ALLOWED_ORIGINS=https://app.sizindomain.com,https://www.sizindomain.com
-```
-
-## İzleme
-
-### Sağlık Kontrolleri
-
-`/health` endpoint'ini izleyin:
-
-```bash
-curl http://localhost:8000/health
-```
-
-Yanıt:
-```json
-{
-  "status": "healthy",
-  "timestamp": "2024-12-26T10:00:00",
-  "uptime_seconds": 3600,
-  "tools_operational": true
-}
-```
-
-### Loglama
-
-Ortam değişkeni ile log seviyesini yapılandırın:
-
-```bash
-LOG_LEVEL=info  # veya debug, warning, error
-```
-
-Loglar şuraya yazılır:
-- Konsol (stdout)
-- `logs/mcp_server.log` dosyası
-
-### Metrikler (Opsiyonel)
-
-OpenTelemetry desteği için:
-
-```bash
-pip install opentelemetry-instrumentation-fastapi
-```
-
-Ortam değişkenlerini ayarlayın:
-```bash
-OTEL_EXPORTER_OTLP_ENDPOINT=http://localhost:4317
-OTEL_SERVICE_NAME=yargi-mcp-server
-```
-
-## Sorun Giderme
-
-### Port Zaten Kullanımda
-
-```bash
-# 8000 portunu kullanan işlemi bulun
-lsof -i :8000
-
-# İşlemi sonlandırın
-kill -9 <PID>
-```
-
-### İzin Hataları
-
-Dosya izinlerinin doğru olduğundan emin olun:
-
-```bash
-chmod +x run_asgi.py
-chown -R www-data:www-data /opt/yargi-mcp
-```
-
-### Bellek Sorunları
-
-Büyük belge işleme için worker belleğini artırın:
-
-```bash
-# systemd servisinde
-Environment="PYTHONMALLOC=malloc"
-LimitNOFILE=65536
-```
-
-### Zaman Aşımı Sorunları
-
-Zaman aşımlarını ayarlayın:
-1. Uvicorn: `--timeout-keep-alive 75`
-2. Nginx: `proxy_read_timeout 300s;`
-3. Cloud sağlayıcılar: Platform özel zaman aşımı ayarlarını kontrol edin
-
-## Performans Ayarlama
-
-### 1. Worker İşlemleri
-
-- Geliştirme: 1 worker
-- Production: CPU çekirdeği başına 2-4 worker
-
-### 2. Bağlantı Havuzlama
-
-Sunucu varsayılan olarak httpx ile bağlantı havuzlama kullanır.
-
-### 3. Önbellekleme (Gelecek Geliştirme)
-
-Redis önbellekleme docker-compose ile etkinleştirilebilir:
-
-```bash
-docker-compose --profile with-cache up
-```
-
-### 4. Veritabanı Zaman Aşımları
-
-`.env` dosyasında veritabanı başına zaman aşımlarını ayarlayın:
-
-```bash
-YARGITAY_TIMEOUT=60
-DANISTAY_TIMEOUT=60
-ANAYASA_TIMEOUT=90
-```
-
