//! Pretty-print the contents of a `.mv2` memvid archive.
//!
//! Usage:
//!
//! ```bash
//! cargo run --example inspect_memory -- path/to/memory.mv2
//! ```
//!
//! Defaults to `chatbot_memory_ollama.mv2` (the file produced by the
//! `chatbot_with_memory_ollama` example) when no argument is given.
