feat: implement webhook path autofixer and improve node similarity service
- Add webhook path auto-generation for nodes missing path configuration - Generates UUID for both 'path' parameter and 'webhookId' field - Conditionally updates typeVersion to 2.1 only when < 2.1 - High confidence fix (95%) as UUID generation is deterministic - Fix critical security and performance issues in NodeSimilarityService: - Replace regex patterns with string-based matching to prevent ReDoS attacks - Add cache invalidation with version tracking to prevent memory leaks - Optimize Levenshtein distance algorithm from O(m*n) space to O(n) - Add early termination for performance improvement - Extract magic numbers into named constants - Add comprehensive documentation for n8n_autofix_workflow tool - Document all fix types including new webhook-missing-path - Include examples, best practices, and warnings - Integrate with MCP tool documentation system - Create node-type-utils for centralized type normalization - Eliminate code duplication across services - Consistent handling of package prefixes 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
