test: add comprehensive test coverage for webhook autofixer and node similarity
- Add test suite for NodeSimilarityService (16 tests) - Tests for common mistake patterns and typo detection - Cache invalidation and expiry tests - Node suggestion scoring and auto-fixable detection - Add test suite for WorkflowAutoFixer (15 tests) - Tests for webhook path generation with UUID - Expression format fixing validation - TypeVersion correction tests - Node type correction tests - Confidence filtering tests - Add test suite for node-type-utils (29 tests) - Package prefix normalization tests - Edge case handling tests All tests passing with correct TypeScript types and interfaces. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
