## Summary
This implementation provides a comprehensive CLI with:
1. **Five main commands** using clap:
- `compute`: Vector/matrix operations, HNSW search, GNN inference
- `benchmark`: Performance testing with detailed metrics
- `convert`: Format conversion (JSON, binary, NumPy, HDF5, etc.)
- `serve`: HTTP REST API server
- `repl`: Interactive shell
2. **Configuration hierarchy**:
- Default values
- TOML config file
- Environment variables
- Command-line arguments (highest priority)
3. **Multiple output formats**:
- Pretty (colored terminal tables)
- JSON
- Binary (bincode)
- CSV
- MessagePack
4. **Full-featured HTTP server**:
- REST API endpoints
- Batch processing
