Implement SQLite database with full-text search for n8n node documentation
Major features implemented: - SQLite storage service with FTS5 for fast node search - Database rebuild mechanism for bulk node extraction - MCP tools: search_nodes, extract_all_nodes, get_node_statistics - Production Docker deployment with persistent storage - Management scripts for database operations - Comprehensive test suite for all functionality Database capabilities: - Stores node source code and metadata - Full-text search by node name or content - No versioning (stores latest only as per requirements) - Supports complete database rebuilds - ~4.5MB database with 500+ nodes indexed Production features: - Automated deployment script - Docker Compose production configuration - Database initialization on first run - Volume persistence for data - Management utilities for operations Documentation: - Updated README with complete instructions - Production deployment guide - Clear troubleshooting section - API reference for all new tools 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
