Hermes Agent CLI - Interactive Terminal Interface

A beautiful command-line interface for the Hermes Agent, inspired by Claude Code.
Features ASCII art branding, interactive REPL, toolset selection, and rich formatting.

Usage:
    python cli.py                          # Start interactive mode with all tools
    python cli.py --toolsets web,terminal  # Start with specific toolsets
    python cli.py --skills hermes-agent-dev,github-auth
    python cli.py -q "your question"       # Single query mode
    python cli.py --list-tools             # List available tools and exit
