test: complete Phase 3 - comprehensive unit test coverage

Browse Source 
- Implemented 943 unit tests across all services, parsers, and infrastructure
- Created shared test utilities (test-helpers, assertions, data-generators)
- Achieved high coverage for critical services:
  - n8n-api-client: 83.87%
  - workflow-diff-engine: 90.06%
  - node-specific-validators: 98.7%
  - enhanced-config-validator: 94.55%
  - workflow-validator: 97.59%
- Added comprehensive tests for MCP tools and documentation
- All tests passing in CI/CD pipeline
- Integration tests deferred to separate PR due to complexity

Total: 943 tests passing, ~30% overall coverage (up from 2.45%)
