fix: Configure WebSocket endpoint from environment variables

## Problem
Frontend was showing 'connecting network' message on production (pezkuwichain.io) because:
1. WebSocket endpoint was hardcoded to localhost in App.tsx
2. DEFAULT_ENDPOINT in polkadot.ts was not reading environment variables

## Solution

### shared/blockchain/polkadot.ts
- Added getWebSocketEndpoint() function to read VITE_NETWORK and corresponding VITE_WS_ENDPOINT_* env vars
- Changed DEFAULT_ENDPOINT from hardcoded value to call getWebSocketEndpoint()
- Now correctly uses wss://ws.pezkuwichain.io in production

### web/src/App.tsx
- Removed hardcoded endpoint="ws://127.0.0.1:9944" prop from PolkadotProvider
- Now uses DEFAULT_ENDPOINT which reads from environment

### web/vite.config.ts
- Minor formatting improvements (no functional changes)

### CLAUDE_README_KRITIK.md (New file)
- Critical documentation for future Claude instances
- Documents VPS validator setup, bootnode configuration
- Strict warnings not to modify working blockchain
- Troubleshooting commands and procedures
- Frontend deployment steps

## Result
- Production site now correctly connects to wss://ws.pezkuwichain.io
- Environment-based configuration working as expected
- Local dev still uses ws://127.0.0.1:9944

## Files Changed
- shared/blockchain/polkadot.ts: Dynamic endpoint selection
- web/src/App.tsx: Remove hardcoded endpoint
- CLAUDE_README_KRITIK.md: Critical documentation (new)

+
+## ⚠️ ÇOK ÖNEMLİ - DOKUNMA!
+
+Bu sistem günlerdir emek verilerek kurulmuştur. Eğer nasıl çalıştığını BİLMİYORSAN hiçbir şeyi **DURDURMA** veya **DEĞİŞTİRME**!
+
+## MEVCUT ÇALIŞAN SİSTEM
+
+### VPS (37.60.230.9) - pezkuwi-vps
+
+**ÇOK ÖNEMLİ:** VPS'te 7 validator çalışıyor ve blok finalize ediyorlar. **BUNLARA DOKUNMA!**
+
+```bash
+# VPS'teki validator durumunu kontrol et:
+ssh pezkuwi-vps "ps aux | grep -E '[p]ezkuwi.*validator'"
+
+# Blockchain durumunu kontrol et:
+ssh pezkuwi-vps "tail -30 /tmp/validator-1.log | grep -E '(peers|finalized)' | tail -5"
+```
+
+**Çalışan validatorlar:**
+- VPS-Validator-1 (Bootnode): Port 30333, RPC 9944
+- VPS-Validator-2: Port 30334, RPC 9945
+- VPS-Validator-3: Port 30335, RPC 9946
+- VPS-Validator-4: Port 30336, RPC 9947
+- VPS-Validator-5: Port 30337, RPC 9948
+- VPS-Validator-6: Port 30338, RPC 9949
+- VPS-Validator-7: Port 30339, RPC 9950
+
+**Chain Spec:** `/root/pezkuwi-sdk/chain-specs/beta/beta-testnet-raw.json`
+
+**Başlatma scripti:** `/tmp/start-vps-with-public-addr.sh`
+
+**Bootnode Peer ID:** `12D3KooWRyg1V1ay7aFbHWdpzYMnT3Nk6RLdM8GceqVQzp1GoEgZ`
+
+### Local PC - 8. Validator (Planlanmış)
+
+Local PC'den 8. validator VPS blockchain'e bağlanacak:
+- Script: `/tmp/start-local-validator-8.sh`
+- Bootnode: `/ip4/37.60.230.9/tcp/30333/p2p/12D3KooWRyg1V1ay7aFbHWdpzYMnT3Nk6RLdM8GceqVQzp1GoEgZ`
+
+## FRONTEND DEPLOYMENT (VPS)
+
+### Production Build Location
+```
+Kaynak: /home/mamostehp/pwap/web
+Build: npm run build
+Deploy: /var/www/pezkuwichain/web/dist/
+```
+
+### Environment
+```
+VITE_NETWORK=testnet
+VITE_WS_ENDPOINT_TESTNET=wss://ws.pezkuwichain.io
+VITE_API_BASE_URL=https://api.pezkuwichain.io/api
+```
+
+### Nginx Config
+```
+Server: /etc/nginx/sites-available/pezkuwichain.io
+Root: /var/www/pezkuwichain/web/dist
+SSL: /etc/letsencrypt/live/pezkuwichain.io/
+```
+
+### WebSocket Proxy
+```nginx
+location /ws {
+    proxy_pass http://127.0.0.1:9944;
+    proxy_http_version 1.1;
+    proxy_set_header Upgrade $http_upgrade;
+    proxy_set_header Connection "upgrade";
+}
+```
+
+## YASAKLAR - BUNLARI YAPMA!
+
+1. ❌ **VPS'teki validatorları DURDURMA!** Blockchain çalışıyor, bozma!
+2. ❌ **Chain spec değiştirme!** `/root/pezkuwi-sdk/chain-specs/beta/beta-testnet-raw.json` kullan
+3. ❌ **Blockchain restart etme!** Eğer gerçekten gerekiyorsa ÖNCE KULLANICIYA SOR
+4. ❌ **Base path değiştirme!** VPS: `/root/pezkuwi-data/beta-testnet/`
+5. ❌ **Varsayımla iş yapma!** Bilmiyorsan SOR!
+
+## SAĞLIKLI BLOCKCHAIN KONTROLÜ
+
+```bash
+# 1. VPS'te validator sayısı (7 olmalı)
+ssh pezkuwi-vps "ps aux | grep -E '[p]ezkuwi.*validator' | wc -l"
+
+# 2. Peer sayısı (6 olmalı - 7 validator birbirine bağlı)
+ssh pezkuwi-vps "tail -30 /tmp/validator-1.log | grep -E 'peers' | tail -1"
+
+# 3. Block finalization (devam ediyor mu?)
+ssh pezkuwi-vps "tail -30 /tmp/validator-1.log | grep -E 'finalized' | tail -3"
+```
+
+**Sağlıklı output örneği:**
+```
+💤 Idle (6 peers), best: #5722, finalized #5720, ⬇ 10.0kiB/s ⬆ 21.2kiB/s
+```
+
+## FRONTEND DEPLOYMENT ADIM ADIM
+
+```bash
+# 1. Local PC'de build (pwap/web klasöründe)
+cd /home/mamostehp/pwap/web
+npm run build
+
+# 2. VPS'e deploy
+rsync -avz dist/ pezkuwi-vps:/var/www/pezkuwichain/web/dist/
+
+# 3. Nginx reload (gerekirse)
+ssh pezkuwi-vps "systemctl reload nginx"
+
+# 4. Kontrol
+curl -I https://pezkuwichain.io
+```
+
+## SORUN GİDERME
+
+### Frontend "connecting network" gösteriyor
+1. Blockchain çalışıyor mu kontrol et (yukarıdaki komutlar)
+2. WebSocket proxy çalışıyor mu: `curl -I http://37.60.230.9:9944`
+3. SSL çalışıyor mu: `curl -I https://pezkuwichain.io`
+
+### Blockchain blok üretmiyor
+- **ÖNCE KULLANICIYA SOR!** Kendi başına restart etme!
+- Peer sayısını kontrol et
+- Session keys set edilmiş mi kontrol et
+
+## CLAUDE, BU KURALLAR SANA:
+
+1. **Eğer bir şey çalışıyorsa DOKUNMA!**
+2. **Bilmiyorsan ÖNCE SOR, sonra yap**
+3. **Varsayım yapma, kanıt topla**
+4. **Kritik işlemlerde ONAY AL**
+5. **Bu dosyayı her session başında OKU**
