test: implement comprehensive testing improvements from PR #104 review

Major improvements based on comprehensive test suite review: Test Fixes: - Fix all 78 failing tests across logger, MSW, and validator tests - Fix console spy management in logger tests with proper DEBUG env handling - Fix MSW test environment restoration in session-management.test.ts - Fix workflow validator tests by adding proper node connections - Fix mock setup issues in edge case tests Test Organization: - Split large config-validator.test.ts (1,075 lines) into 4 focused files - Rename 63+ tests to follow "should X when Y" naming convention - Add comprehensive edge case test files for all major validators - Create tests/README.md with testing guidelines and best practices New Features: - Add ConfigValidator.validateBatch() method for bulk validation - Add edge case coverage for null/undefined, boundaries, invalid data - Add CI-aware performance test timeouts - Add JSDoc comments to test utilities and factories - Add workflow duplicate node name validation tests Results: - All tests passing: 1,356 passed, 19 skipped - Test coverage: 85.34% statements, 85.3% branches - From 78 failures to 0 failures 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
