DeepBase SQLite Driver

SQLite database driver for DeepBase providing high-performance, ACID-compliant storage for nested JavaScript objects. Uses better-sqlite3 with synchronous operations wrapped in async API. Supports PRAGMA modes (none, safe, balanced, fast) for tuning durability vs performance. Includes singleton pattern for shared connections across instances. Current stable version: 3.6.9. Active development with regular releases. Key differentiator: seamlessly integrates with DeepBase's nested object storage using dot-notation path indexing and monotonic sequence ordering for deterministic key order.
