feat: add complete silent mode for TUI applications

- Add silent option to BrainyConfig to suppress ALL console output
- Override console methods (log, info, warn, error) when silent=true
- Add LogLevel.SILENT to Logger for proper silent mode support
- Propagate silent mode to all augmentations automatically
- Update augmentation configs to support silent property
- Restore console methods properly on brain.close()
- Perfect for terminal UI applications that need clean output

Usage:
```javascript
const brain = new Brainy({
  storage: { type: 'filesystem', path: './data' },
  silent: true  // Complete silence - zero console output
})
```
