//! SQLite-based protocol/database system for RustyNeuro session persistence
//!
//! This crate provides persistence for MEG/EEG analysis sessions, similar to
//! Brainstorm's protocol system. It stores:
//!
//! - Protocols (top-level containers)
//! - Subjects with demographics and anatomy paths
//! - Recordings with metadata
//! - Epochs, forward models, inverse operators
//! - SSP projectors and ICA models
//!
//! # Example
//!
//! ```no_run
//! use rtx_neuro_db::NeuroDatabase;
//! use std::path::PathBuf;
//!
//! #[tokio::main]
//! async fn main() -> Result<(), Box<dyn std::error::Error>> {
//!     // Open or create database
//!     let db = NeuroDatabase::open("my_protocol.db").await?;
//!
//!     // Create a protocol
//!     let protocol = db.create_protocol("My Study", PathBuf::from("/data/study")).await?;
//!
//!     // Add subjects
//!     let subject = db.create_subject(&protocol.id, "sub-01").await?;
//!     db.set_subject_anatomy(&subject.id, Some("/freesurfer/sub-01".to_string())).await?;
//!
//!     // List all protocols
//!     let protocols = db.list_protocols().await?;
//!     println!("Found {} protocols", protocols.len());
//!
//!     Ok(())
//! }
//! ```
