feat: integrate database cache into CLI startup logic

� Cache Integration Enhancements:
- Modify get_cache() to use IntegratedCacheManager by default
- Automatic fallback from database cache to file cache
- Intelligent cache selection based on configuration

� Integration Features:
- IntegratedCacheManager now used in CLI startup
- Supports both database and file-based caching
- Automatic detection of database availability
- Graceful degradation when databases unavailable

✅ Test Results:
- Cache selection logic: ✅ Pass
- Cache functionality: ✅ Pass
- Database cache available but disabled by default
- File cache working as fallback

� User Experience:
- Default: File-based cache (fast, no setup required)
- Optional: Database cache (enable with MONGODB_ENABLED=true)
- Seamless transition between cache types
- No breaking changes to existing functionality

� Current Status:
- Cache Type: IntegratedCacheManager
- Adaptive Cache: Disabled (databases disabled in .env)
- MongoDB: Disabled by default
- Redis: Disabled by default
- Fallback: Traditional file cache working perfectly

Now users get database cache benefits when enabled,
with automatic fallback to reliable file cache.
