Fix web build: React 19 JSX runtime + AuthContext hooks order

- babel.config.js: changed jsxRuntime from 'classic' to 'automatic' (React 19 requirement)
- AuthContext.tsx: reordered useEffect/useCallback to fix "Cannot access 'checkAuth' before initialization" error on web
- CLAUDE.md: added Quick Start, Git Workflow, Credentials sections

Web version now builds and runs correctly with npm run web

 # WellNuo - Project Architecture
 
+## Quick Start
+
+```bash
+cd /Users/sergei/Desktop/WellNuo
+git pull origin development  # всегда сначала pull!
+npm run web                  # Web-First подход
+# Откроется http://localhost:8081
+```
+
+---
+
+## Git Workflow (ОБЯЗАТЕЛЬНО!)
+
+**Branch:** `development`
+
+### Перед началом работы:
+```bash
+git pull origin development
+```
+
+### После изменений:
+```bash
+git add <файлы>
+git commit -m "описание"
+git push origin development
+```
+
+### Правило одной сессии:
+**Только ОДИН Claude Code работает с этим проектом одновременно!**

+## Текущий статус (12.01.2026)
+
+### Работает:
+- [x] Web версия (`npm run web`)
+- [x] Login экран
+- [x] Backend API
+
+### TODO (Web-First):
+- [ ] SecureStore → localStorage (HIGH!)
+- [ ] ImagePicker → File Input
+- [ ] WebView → iframe
+- [ ] Stripe.js для web
+
+### Исправленные баги:
+1. `babel.config.js` — jsxRuntime: 'automatic'
+2. `AuthContext.tsx` — порядок hooks
