Enhanced NPM Installer Patch for v0.7.2
=========================================

PROBLEM: Users installing v0.7.1 get "Framework not properly deployed" and "Memory System: ❌ Not configured" errors

SOLUTION: Add memory system setup and framework initialization to postinstall.js

REQUIRED ADDITIONS:
1. setupMemorySystem() function (see above)
2. Call setupMemorySystem() in main installation workflow
3. Call initializeFramework() after component deployment
4. Add memory system validation to health checks

INTEGRATION POINTS:
- Add after deployFrameworkCore() call
- Add before final validation
- Update validation results to include memory system

IMPLEMENTATION:

    /**
     * Deploy and initialize memory system components
     * Critical for bug tracking and user feedback collection
     */
    async setupMemorySystem() {
        try {
            this.log('🧠 Setting up memory system...');

                path.join(this.globalConfigDir, 'memory', 'backups')
            ];
            
            for (const dir of memoryDirs) {
                await fs.mkdir(dir, { recursive: true });
                this.log(`   ✅ Created memory directory: ${dir}`);
