LaminarDB Storage

Durability layer for LaminarDB - WAL, checkpointing, and recovery.

Module Overview

• [wal]: Write-ahead log for durability and exactly-once semantics
• [checkpoint]: Basic checkpointing for fast recovery
• [incremental]: F022 Incremental checkpointing with RocksDB backend
• [per_core_wal]: F062 Per-core WAL segments for thread-per-core architecture
• [wal_state_store]: Combines MmapStateStore with WAL for durability

Note: Lakehouse sinks (Delta Lake, Iceberg) are in laminar-connectors crate, not here. This crate handles LaminarDB's internal durability, not external storage formats.
