✅ Persistent state to avoid repeated prompts
✅ Manual access via Window menu
✅ Version-aware setup completion tracking

### 3. Installation Orchestrator
**Location**: `UnityMcpBridge/Editor/Installation/`

#### Components:
- **InstallationOrchestrator.cs**: Guided installation workflow

#### Features:
✅ Asset Store compliant (no automatic downloads)
✅ Progress tracking and user feedback
✅ Platform-specific installation guidance
✅ Error handling and recovery suggestions

### 4. Asset Store Compliance
#### Package Structure Changes:
✅ Updated package.json to remove Python references
✅ Added dependency requirements to description
✅ Clean separation of embedded vs external dependencies
✅ No bundled executables or large binaries

#### User Experience:
✅ Clear setup requirements communication
✅ Guided installation process
✅ Fallback modes for incomplete installations
✅ Comprehensive error messages with actionable guidance

### 5. Integration with Existing System
#### Maintained Compatibility:
✅ Integrates with existing ServerInstaller
✅ Uses existing McpLog infrastructure
✅ Preserves all existing MCP functionality
✅ No breaking changes to public APIs

#### Enhanced Features:
✅ Menu items for dependency checking
✅ Diagnostic information collection
✅ Setup state persistence
✅ Platform-aware installation guidance

## Key Features Implemented

### 1. Automatic Dependency Detection
- **Multi-platform support**: Windows, macOS, Linux
- **Intelligent path resolution**: Common installation locations + PATH
- **Version validation**: Ensures Python 3.10+ compatibility
- **Comprehensive diagnostics**: Detailed status information

### 2. User-Friendly Setup Wizard
- **Progressive disclosure**: 5-step guided process
- **Visual feedback**: Progress bars and status indicators
- **Persistent state**: Avoids repeated prompts
- **Manual access**: Available via Window menu

### 3. Asset Store Compliance
- **No bundled dependencies**: Python/UV not included in package
- **External distribution**: MCP server as source code only
- **User-guided installation**: Clear instructions for each platform
- **Clean package structure**: Minimal size impact

### 4. Error Handling & Recovery
- **Graceful degradation**: System works with partial dependencies
- **Clear error messages**: Actionable guidance for users
- **Diagnostic tools**: Comprehensive system information
- **Recovery suggestions**: Platform-specific troubleshooting

## Testing & Validation

### Test Infrastructure:
✅ DependencyManagerTests.cs with menu-driven test execution
✅ Basic functionality validation
✅ Setup wizard testing
✅ State management testing

### Manual Testing Points:
- [ ] First-time user experience
- [ ] Cross-platform compatibility
