feat: Implement n8n-MCP Enhancement Plan v2.1 Final
- Implement simple node loader supporting n8n-nodes-base and langchain packages - Create parser handling declarative, programmatic, and versioned nodes - Build documentation mapper with 89% coverage (405/457 nodes) - Setup SQLite database with minimal schema - Create rebuild script for one-command database updates - Implement validation script for critical nodes - Update MCP server with documentation-focused tools - Add npm scripts for streamlined workflow Successfully loads 457/458 nodes with accurate documentation mapping. Versioned node detection working (46 nodes detected). 3/4 critical nodes pass validation tests. Known limitations: - Slack operations extraction incomplete for some versioned nodes - One langchain node fails due to missing dependency - No AI tools detected (none have usableAsTool flag) 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
