Struct TransactionManager 

pub struct TransactionManager { /* private fields */ }

Transaction Manager (in-memory, no WAL durability)

Manages transaction lifecycle and provides ACID guarantees for in-memory operations. This implementation does NOT include WAL integration.

For production workloads requiring durability, use [sochdb_storage::MvccTransactionManager] which includes:

• Write-ahead logging for crash recovery
• Serializable Snapshot Isolation (SSI)
• Group commit for high throughput
• Event-driven async architecture
