Oook CLI - Smart Home System Testing Interface

STATUS: ✅ Production Ready - All commands operational

ARCHITECTURE:
Rich command-line interface for The Goodies smart home system providing
comprehensive server testing, MCP tool execution, and graph exploration
with formatted output and interactive capabilities.

CORE FUNCTIONALITY:
- Execute all 12 MCP tools with argument parsing
- Populate graph database with realistic test data
- Display server statistics and entity counts
- Search entities with full-text search
- Create entities and relationships interactively
- Monitor server health and performance

KEY FEATURES:
- Rich console formatting with tables and panels
- JSON syntax highlighting for responses
- Interactive tool execution with validation
- Graph visualization and statistics
- Development utilities and debugging tools
