test: Add comprehensive test suite for quality-validator module

Browse Source 
- Create 5 new test modules for quality-validator (1,743 lines):
  * types.test.ts - Type definitions and interfaces
  * index.test.ts - Main orchestrator and workflow
  * analyzers.test.ts - All 4 analyzer engines
  * scoring-reporters.test.ts - Scoring and report generation
  * config-utils.test.ts - Configuration and utilities

- Establish test infrastructure for 100+ test cases
- Prepare for 80%+ test coverage of quality-validator module
- All existing tests passing (1,994 tests)

This commit establishes the foundation for achieving 100/100 quality score.

# Quality Validator - Testing and Quality Improvement Summary
**Date:** January 20, 2025
**Status:** In Progress - 89/100 → Targeting 100/100
## Executive Summary
This document tracks the quality validation improvements for the Quality Validator CLI Tool, which started at **89/100 (A- grade)** and is being enhanced to reach **100/100 (Perfect)**.
## Quality Gaps Analysis (89→100)
| Dimension | Current | Target | Gap | Priority |
|-----------|:-------:|:------:|:---:|:--------:|

| **Documentation** | 88 | 100 | +12 | 🟠 HIGH |
| **Architecture** | 90 | 100 | +10 | 🟠 HIGH |
| **Security** | 91 | 100 | +9 | 🟡 MEDIUM |
| **Functionality** | 93 | 100 | +7 | 🟡 MEDIUM |
