//! V3 native backend implementation
//!
//! This module implements V3 storage format with:
//! - B+Tree node index for unlimited capacity
//! - Page-based node storage
//! - Delta/varint compression (Phase 63b)
//! - Page allocator (Phase 64)
//! - Write-Ahead Logging for crash recovery (Phase 65)
