feat: add n8n integration with MCP Client Tool support
- Add N8N_MODE environment variable for n8n-specific behavior - Implement HTTP Streamable transport with multiple session support - Add protocol version endpoint (GET /mcp) for n8n compatibility - Support multiple initialize requests for stateless n8n clients - Add Docker configuration for n8n deployment - Add test script with persistent volume support - Add comprehensive unit tests for n8n mode - Fix session management to handle per-request transport pattern BREAKING CHANGE: Server now creates new transport for each initialize request when running in n8n mode to support n8n's stateless client architecture 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
