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
