v2.0.2: Settings Revamp, Restore Addon Only, Reset Tab Enhancements

 New Features:
- Settings restructured into 4 categories (General, Behavior, Sessions, Experimental)

+## 🆕 Feature: Restore Addon Only
+
+### Overview
+Restore ONLY addon folders from a backup session, without touching the main data folder.
+
+### Use Case
+User wants to restore `.aws` credentials from backup without restoring entire VSCode settings.
+
+### Requirements
+1. **Setting enabled**: `Experimental > Show Restore Addon Only = ON`
+2. **App has addon paths**: `addon_backup_paths` not empty
+3. **Session has addons**: `_addons` folder exists in backup
+
+### UI Flow
+
+**Right-click Context Menu (Sessions Tab)**:
+```
+┌─────────────────────────────┐
+│ 📦 Restore Session          │
+│ 👤 Restore Account Only     │
+│ 📁 Restore Addon Only       │ ← NEW (conditional)
+│ ─────────────────────────── │
+│ ✓ Set as Active             │
+│ 📂 Open Folder              │
+│ ─────────────────────────── │
+│ 🗑️ Delete Session           │
+└─────────────────────────────┘
+```
+
+**Visibility Logic**:
+```javascript
+showRestoreAddonOnly = 
+  settings.experimental.showRestoreAddonOnly === true &&
+  app.addon_backup_paths.length > 0 &&
+  sessionHasAddonsFolder(session)
+```
+
+### Backend Implementation
+
+**New Function**: `RestoreAddonOnly(appKey, sessionName, skipClose)`
+
+```go
+func (a *App) RestoreAddonOnly(appKey, sessionName string, skipClose bool) error {
+    cfg := a.GetApp(appKey)
+    if cfg == nil {
+        return fmt.Errorf("app not found: %s", appKey)
+    }
+
+    if len(cfg.AddonPaths) == 0 {
+        return fmt.Errorf("no addon paths configured")
+    }
+
+    // Close app if needed
+    if !skipClose {
+        // ... close logic
+    }
+
+    // Restore ONLY addons from backup
+    backupFolder := filepath.Join(m.backupPath, appKey, sessionName)
+    return m.restoreAddons(backupFolder, cfg.AddonPaths, progressCb)
+}
+```
+
+### Confirmation Dialog
+
+```
+┌─────────────────────────────────────────┐
+│  Restore Addon Folders Only             │

+│  "session-name"                         │
+│                                         │
+│  This will restore:                     │
+│  • C:\Users\User\.aws                   │
+│  • C:\Users\User\.ssh                   │
+│                                         │
+│  Main data folder will NOT be touched.  │
+│                                         │
+│  ┌─────────┐  ┌─────────┐              │

+
+## 🧪 Testing Scenarios
+
+### Restore Addon Only
+1. ✅ App with addon paths + session with _addons → Show menu item
+2. ✅ App without addon paths → Hide menu item
+3. ✅ Session without _addons folder → Hide menu item
+4. ✅ Setting disabled → Hide menu item
+5. ✅ Restore only addons, verify data folder untouched
+6. ✅ Handle missing addon paths gracefully
+
+### Import/Export Settings
+1. ✅ Export settings to JSON
+2. ✅ Import valid JSON
+3. ✅ Import invalid JSON → Show error
+4. ✅ Import with missing fields → Use defaults
+5. ✅ Preview changes before import
+
+---
+
+## 📝 Notes
+
+- **Backward Compatibility**: Old settings format should still work
+- **Migration**: Auto-migrate old settings to new structure
+- **Validation**: Validate all imported settings before applying
+- **Backup**: Always backup current settings before import
+
+---
+
+## ✅ Acceptance Criteria
+
+- [ ] Settings page has 4 categories (General, Behavior, Sessions, Experimental)
+- [ ] Import/Export settings works correctly
+- [ ] "Restore Addon Only" appears in context menu when conditions met
+- [ ] "Restore Addon Only" restores ONLY addon folders
+- [ ] All existing settings still work after revamp
+- [ ] Settings are persisted correctly
+- [ ] UI is clean and intuitive
+
+---
+
+## 🚀 Future Enhancements
+
+1. **Cloud Sync Settings** - Sync settings across devices
+2. **Settings Profiles** - Multiple setting profiles (Work, Personal, etc.)
+3. **Scheduled Auto-backups** - Automatic backup on schedule
+4. **Backup Compression** - Compress backups to save space
+5. **Backup Encryption** - Encrypt sensitive backups
