chore: reorganize docs folder + add CLAUDE.md

- Kelompokkan docs/ ke subfolder: architecture/, testing/, notes/, ai/, tasks/
- Pindahkan tasks/ (root) ke docs/tasks/
- Tambah docs/README.md sebagai index navigasi
- Tambah CLAUDE.md (project instructions)
- Hapus .qwen/settings.json

+# Task: TASK-002 - Expo Router Tabs Safe Area Fix
+
+## 📋 Deskripsi
+
+Expo Router Tabs di beberapa fitur (Event, Job, Voting, Donation, Investment) tertutup oleh navigation buttons Android pada device tertentu.
+
+## 🎯 Tujuan
+
+Tabs di semua fitur menggunakan Expo Router harus responsif dan tidak tertutup navigation buttons Android.
+
+## 🔍 Analisis Masalah
+
+### Fitur yang Terkena Dampak
+
+| Fitur | Layout File | Status |
+|-------|-------------|--------|
+| Event | `app/(application)/(user)/event/(tabs)/_layout.tsx` | ❌ Tidak responsif |
+| Job | `app/(application)/(user)/job/(tabs)/_layout.tsx` | ❌ Tidak responsif |
+| Voting | `app/(application)/(user)/voting/(tabs)/_layout.tsx` | ❌ Tidak responsif |
+| Donation | `app/(application)/(user)/donation/(tabs)/_layout.tsx` | ❌ Tidak responsif |
+| Investment | `app/(application)/(user)/investment/(tabs)/_layout.tsx` | ❌ Tidak responsif |
+| Collaboration | `app/(application)/(user)/collaboration/(tabs)/_layout.tsx` | ❌ Tidak responsif |
+
+### Root Cause
+
+`TabsStyles` di `styles/tabs-styles.ts` tidak menghormati safe area insets Android dengan benar.
+
+## 📝 Solusi
+
+### Opsi 1: Custom Tab Bar Component (RECOMMENDED)
+
+Buat custom `tabBar` component yang menggunakan `SafeAreaView` untuk wrapping tab bar.
+
+```typescript
+// styles/tabs-styles.ts
+import { useSafeAreaInsets } from 'react-native-safe-area-context';
+
+export function CustomTabBar(props: any) {
+  const insets = useSafeAreaInsets();
+  
+  return (
+    <View style={{ 
+      paddingBottom: insets.bottom,
+      backgroundColor: MainColor.darkblue 
+    }}>
+      <BottomTabBar {...props} />
+    </View>
+  );
+}
+```
+
+### Opsi 2: Update tabBarStyle dengan insets
+
+Tambahkan dynamic height berdasarkan safe area insets.
+
+## ✅ Acceptance Criteria
+
+1. Tabs tidak tertutup navigation buttons Android
+2. Tabs height konsisten di semua device
+3. Tidak ada regression di iOS
+4. Semua 6 fitur ter-fix
+
+## 🔄 Status
+
+**Status**: ✅ COMPLETED
+**Created**: 2026-04-01
+**Updated**: 2026-04-01
+**Completed**: 2026-04-01
+
+## 📝 Implementation Summary
+
+### Changes Made
+
+**Tabs Layout Wrappers** - Updated 6 layout files dengan safe area handling:
+- ✅ `app/(application)/(user)/event/(tabs)/_layout.tsx`
+- ✅ `app/(application)/(user)/job/(tabs)/_layout.tsx`
+- ✅ `app/(application)/(user)/voting/(tabs)/_layout.tsx`
+- ✅ `app/(application)/(user)/donation/(tabs)/_layout.tsx`
+- ✅ `app/(application)/(user)/investment/(tabs)/_layout.tsx`
+- ✅ `app/(application)/(user)/collaboration/(tabs)/_layout.tsx`
+
+### Implementation Pattern
+
+Setiap layout file menggunakan wrapper component pattern:
+
+```typescript
+function TabsWrapper() {
+  const insets = useSafeAreaInsets();
+  const paddingBottom = Platform.OS === "android" ? insets.bottom : 0;
+
+  return (
+    <View style={{ flex: 1, backgroundColor: MainColor.darkblue }}>
+      <Tabs screenOptions={TabsStyles}>
+        {/* Tabs content */}
+      </Tabs>
+      {/* Safe area padding untuk Android */}
+      {Platform.OS === "android" && paddingBottom > 0 && (
+        <View style={{ height: paddingBottom, backgroundColor: MainColor.darkblue }} />
+      )}
+    </View>
+  );
+}
+```
+
+### Files Changed
+- ✅ 6x Tabs layout files (Updated with safe area wrapper)
+
+### Test Results
+- ✅ TypeScript compilation: No errors
+- ✅ All 6 tabs layouts: Safe area implemented
+- ✅ Platform-specific: Android only (iOS unaffected)
+- ✅ NewWrapper: Unchanged (original version preserved)
+
+### Features Fixed
+
+| Feature | Layout File | Status |
+|---------|-------------|--------|
+| Event | `app/(application)/(user)/event/(tabs)/_layout.tsx` | ✅ Fixed |
+| Job | `app/(application)/(user)/job/(tabs)/_layout.tsx` | ✅ Fixed |
+| Voting | `app/(application)/(user)/voting/(tabs)/_layout.tsx` | ✅ Fixed |
+| Donation | `app/(application)/(user)/donation/(tabs)/_layout.tsx` | ✅ Fixed |
+| Investment | `app/(application)/(user)/investment/(tabs)/_layout.tsx` | ✅ Fixed |
+| Collaboration | `app/(application)/(user)/collaboration/(tabs)/_layout.tsx` | ✅ Fixed |
+
+### Next Steps for User Testing
+
+Test all 6 features on physical Android devices with:
+- [ ] Navigation buttons (back, home, recent)
+- [ ] Gesture navigation
+- [ ] Various screen sizes
+
+Test on iOS to ensure no regression:
+- [ ] Home button devices
+- [ ] Gesture devices (notch)
