//! Transaction support for atomic indexing operations
//!
//! This module provides transactional guarantees for index updates,
//! ensuring that either all changes are committed or none are.
//!
//! With Tantivy-only architecture, transactions are handled by Tantivy's
//! writer commit system, so this is now a lightweight compatibility layer.

/// A transaction that can be committed or rolled back
///
/// In the Tantivy-only architecture, this is a lightweight wrapper
/// since Tantivy handles transactions internally through its writer.
