## 🎮 Unified Interface

### Old Usage (4 separate tools):
```bash
./gwemplate                    # Fast AV1 encoding
./gwenquick --web              # Web-optimized encoding
./gwenquick --quick            # Quick encoding
./gwenquick --tiny             # Tiny file encoding
./gwencode_v2                  # Full interactive mode
./gwripper                     # YouTube downloading
```

### New Usage (1 unified tool):
```bash
./gwencoder --fast             # Fast AV1 encoding (gwemplate)
./gwencoder --web              # Web-optimized encoding (gwquick --web)
./gwencoder --quick            # Quick encoding (gwquick --quick)
./gwencoder --tiny             # Tiny file encoding (gwquick --tiny)
./gwencoder --full             # Full interactive mode (GWEncoder.go)
./gwencoder --help             # Help information
./gwencoder --info             # System information
./gwencoder --stats            # Encoding statistics
```

## 📁 Shared Utilities Package (gwutils)

- `Prompt()` - User input with defaults
- `GetVideoInfo()` - Get video resolution and codec info
- `GetPhysicalCores()` - Calculate physical CPU cores
- `CheckFFmpeg()` / `CheckFFprobe()` - Check tool availability

### Configuration (`config.go`):
- `Config` struct - Unified configuration structure
