feat: Complete Strategic Roadmap Implementation for HolyGrailRequirement

⭐ MAJOR ORGANIZATIONAL MILESTONE

## Strategic Roadmap Complete
- Created ROADMAP.md with 4-subproject strategic framework
- Updated ProjectStatusDigest.md with milestone integration
- Organized 4 strategic subprojects in Gitea as milestones
- Assigned all existing issues to appropriate subprojects
- Set priority levels (CRITICAL/HIGH/MEDIUM/LOW) based on roadmap

## Gitea Project Management Setup
- ✅ Issue #14 closed with TDD8 workflow complete
- ✅ 4 strategic milestones created:
  - Schema-Driven Architecture (3 issues)
  - Template & Stub Generation (1 issue)
  - Document Relationships (2 issues)
  - Plan-Actual Comparison Engine (3 issues)
- ✅ Project management labels and priorities configured
- ✅ Strategic issue organization targeting arc42 documentation system

## Strategic Value
Transforms project from strong technical foundation (125+ tests, complete
document manipulation) into structured progression toward HolyGrailRequirement:
AI-supported arc42 architecture documentation system with plan-actual
comparison capabilities.

## Ready for Implementation
Clear development path established with CRITICAL priorities:
- Issue #13: Cache Management CLI Commands
- Issue #15: AST Query and Analysis CLI

 ## 🚀 **Next Development Phase: Advanced CLI & Query Features**
 
-### Phase 3: Database Query Interface (Immediate Priority)
-**Issue #14: Database Query CLI Interface**
-- **Objective**: Deliver "Relational Document Metadata" core USP
-- **Scope**: SQL query interface for metadata operations and file relationships
-- **Value**: Users can query stored documents using database operations
-- **Foundation**: Build on DatabaseManager schema and completed AST caching system
-- **Strategic Value**: Transforms metadata storage into powerful query capabilities
+### Phase 3: Database Query Interface ⭐ COMPLETE - TDD8 CYCLE FINISHED
+**Issue #14: Database Query CLI Interface - READY FOR GITEA CLOSURE**
+- ✅ **Implementation**: Complete SQL query interface with security constraints
+- ✅ **Commands**: `query`, `schema`, `metadata` with table/JSON/YAML output formats
+- ✅ **Testing**: 35 comprehensive tests (100% passing)
+- ✅ **Security**: SQL injection prevention and read-only enforcement
+- ✅ **Documentation**: Full docstrings with examples and security notes
+- ✅ **Quality Assurance**: All Issue #14 tests passing, integration verified
+- ✅ **Value Delivered**: Users can query stored documents using database operations
 
-**Implementation Strategy:**
-1. Run `make tdd-start NUM=14` to begin database query implementation
-2. Add SQL query interface and metadata search commands to CLI
-3. Provide relationship mapping and content discovery operations
-4. Integrate with existing DatabaseManager and cached AST data
+**🎯 TDD8 CYCLE COMPLETE:**
+- ✅ **ISSUE**: Requirements defined and understood
+- ✅ **TEST**: 35 comprehensive tests covering all functionality
+- ✅ **RED**: Tests initially failed during development
+- ✅ **GREEN**: Implementation completed - all commands working
+- ✅ **REFACTOR**: Code quality maintained throughout
+- ✅ **DOCUMENT**: Complete docstrings with usage examples
+- ✅ **REFINE**: Quality checks passed, 35/35 tests passing
+- ✅ **PUBLISH**: TDD8 workflow formally completed
+
+**🔄 NEXT ACTION REQUIRED:**
+**Use `project-assistant` to close Issue #14 in Gitea and update milestone status**
