test: Phase 3 - Create comprehensive unit tests for services

- Add unit tests for ConfigValidator with 44 test cases (95.21% coverage)
- Create test templates for 7 major services:
  - PropertyFilter (23 tests)
  - ExampleGenerator (35 tests)
  - TaskTemplates (36 tests)
  - PropertyDependencies (21 tests)
  - EnhancedConfigValidator (8 tests)
  - ExpressionValidator (11 tests)
  - WorkflowValidator (9 tests)
- Fix service implementations to handle edge cases discovered during testing
- Add comprehensive testing documentation:
  - Phase 3 testing plan with priorities and timeline
  - Context documentation for quick implementation
  - Mocking strategy for complex dependencies
- All 262 tests now passing (up from 75)
