feat: Complete Issue #50 - Define metaschema for JSON schema structure
Implement comprehensive MarkiTect metaschema that extends standard JSON Schema with MarkiTect-specific features for document analysis and generation. 🎯 TDD8 Implementation Complete: - ISSUE: Analyzed existing schema system and requirements - TEST: 15 comprehensive tests covering all features - RED: Verified tests fail before implementation - GREEN: Implemented metaschema JSON and validation logic - REFACTOR: Clean, extensible validator architecture - DOCUMENT: Updated CLI help and comprehensive documentation - REFINE: 100% test success rate and CLI integration - PUBLISH: Ready for production use ✅ Key Features Implemented: - Heading text capture support (x-markitect-heading-text) - Content field instructions (x-markitect-content-instructions) - Outline structure representation (x-markitect-outline-mode/depth) - Backward compatibility with existing schemas - Validation rules for all new features - CLI integration in schema-ingest command 📁 Files Added: - markitect/metaschema.py - Validation logic and MetaschemaValidator - markitect/schemas/markitect-metaschema.json - Metaschema definition - Enhanced markitect/cli.py - Automatic metaschema validation 🧪 Testing: - 15 comprehensive tests (100% passing) - RED-GREEN-REFACTOR cycle validated - CLI integration tested and working - Backward compatibility verified 📋 Acceptance Criteria Met: ✅ Schema metaschema supports heading text capture ✅ Schema metaschema supports content field instructions ✅ Schema metaschema supports outline structure representation ✅ Schema metaschema is backward compatible with existing schemas ✅ Schema metaschema includes validation rules for new features ✅ Documentation explains the metaschema structure and usage 🔗 Foundation for Future Issues: - Issue #51: Outline mode schema generation - Issue #52: Heading text capture in schemas - Issue #54: Content instruction capabilities - Issue #55: Schema-based draft generation 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
