 //! Generic transaction module for atomic operations across multiple stores.
 //!
 //! # Example
 //!
 //! This module provides a generic transaction mechanism for atomic operations across
 //! different types of stores. Each store implementation can plug into this system
 //! by implementing the `TransactionProvider` trait.
 //!
 //! ```no_run
 //! use store::{Transaction, TransactionContext};
 //! 
 //! // Assuming you have stores and trees
 //! # fn example_usage() -> store::Result<()> {
 //! # let temp_dir = tempfile::tempdir().unwrap();
 //! # let db = sled::open(temp_dir.path())?;
 //! # let range_store = store::RangeStore::open(&db)?;
 //! # let namespace_store = store::NamespaceStore::open(&db)?;
 //! # let metadata_tree = db.open_tree("metadata")?;
 //!
 //! // Create a transaction with the stores you want to include
 //! let transaction = Transaction::new()
 //!     .with_store("ranges", &range_store)
 //!     .with_store("namespaces", &namespace_store)
 //!     .with_tree(&metadata_tree);
 //!
 //! // Execute the transaction
 //! let result = transaction.execute(|ctx| {
 //!     // Access stores by name
 //!     let range_trees = ctx.store_trees("ranges")?;
 //!     let namespace_trees = ctx.store_trees("namespaces")?;
 //!     
 //!     // Access additional trees by index
 //!     let metadata = ctx.tree(0)?;
 //!     
 //!     metadata.insert("operation", "test")

+//!     .with_config("type", "aws")
