…to top of file - Move getDatabase import from dynamic import inside processChecksumWithTimeout method to top-level imports - Fixes 'Cannot read properties of undefined (reading transaction)' error affecting 1,876 pending checksums - Follows best practice of placing all imports at file top rather than using dynamic imports inside methods - Verified checksum processing now works correctly with database transactions Co-Authored-By: mark.gilbert@prominic.net <mark.gilbert@prominic.net>
… transaction bug - Fix critical checksum processing bug by moving getDatabase import to top of fileWatcher.js - Add database-agnostic PRAGMA optimize support for SQLite with PostgreSQL/MySQL compatibility - Implement composite indexes for search query optimization (file_path + checksum_sha256) - Add in-memory caching service with LRU eviction and TTL for directory listings - Enhance search functionality with pagination support (page, limit, total count) - Create maintenance service for scheduled database optimization (24-hour intervals) - Integrate cache invalidation on file changes for optimal performance - Improve checksum queue processing with better concurrent batching Resolves transaction errors affecting 1,876 pending checksums in production. All optimizations are database-dialect agnostic and work with SQLite, PostgreSQL, and MySQL. Co-Authored-By: mark.gilbert@prominic.net <mark.gilbert@prominic.net>

Fix critical checksum transaction bug and implement comprehensive database optimizations
Summary
This PR addresses a critical production bug causing 1,876 pending checksums to fail with transaction errors, while implementing comprehensive database optimizations based on SQLite documentation recommendations and production performance analysis.
Critical Bug Fix:
