Add comprehensive COBOL analysis documentation for Holidays module

[Copilot]

Generates multi-dimensional analysis of the Canada Day Calculator COBOL module (CANDAY01.CBLLE, TESTCDAY.CBLLE) covering code structure, dependencies, testing maturity, and modernization paths.

Analysis Documents Added

5 documents, 151 KB, ~4,900 lines:

• ANALYSIS-INDEX.md - Navigation guide with role-based entry points (PM, Dev, QA, Architect)
• README.md - Executive summary with risk matrix and 4-phase modernization roadmap
• CANDAY01-Analysis.md - Code structure analysis (Rating: 8.55/10, Maintainability: 82/100)
• TESTCDAY-Analysis.md - Testing framework assessment (Grade: D, 15% complete, 40-80hr roadmap)
• Holidays-Dependency-Analysis.md - Architecture analysis (Grade: B-, no circular deps, coupling metrics)

Key Findings

CANDAY01 - Production quality with minor improvements needed:

• ✅ Clean modular design, no GOTOs, COBOL-85 compliant
• ⚠️ Unused variable (WS-DATE-FORMATTED), magic numbers

TESTCDAY - Skeleton implementation requiring completion:

• 🔴 No actual CALL to CANDAY01, no validation logic
• 🔴 Test data defined but never executed

Architecture - Solid foundation with integration gaps:

• ✅ Zero circular dependencies, minimal external coupling
• 🔴 Missing LINKAGE SECTION prevents programmatic invocation
• 🔴 Console I/O coupling limits reusability

Analysis Coverage

Each document includes:

• Quality metrics (cyclomatic complexity, maintainability index, LOC)
• Dependency mapping and risk assessment
• Prioritized recommendations with effort estimates
• Code samples and refactoring patterns
• Cross-references between analyses

Estimated remediation effort: 180-260 hours across 4 phases (immediate fixes → generalization).
