fix: normalize node type prefixes for n8n workflow exports (#71)
- Add centralized normalizeNodeType utility to handle prefix conversion - n8n-nodes-base.* → nodes-base.* - @n8n/n8n-nodes-langchain.* → nodes-langchain.* - Update all 9 affected MCP tools to use normalized node types - AI agents can now use node types directly from n8n workflow exports - Maintains backward compatibility with existing shortened prefixes - Add comprehensive test coverage for all affected methods Fixes #71 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
