This implementation enhances the existing generate-stub command to utilize
content field instructions from schemas, providing guided document generation
with specific placeholder text instead of generic "TODO" messages.

## Key Features Added:

### Enhanced Schema-Based Generation
- Content instructions from schemas (x-markitect-content-instructions) are now used
- Schema reference metadata included in generated drafts for traceability
- Intelligent fallback to generic placeholders for schemas without instructions
- Full integration with existing generate-stub CLI command and options

### StubGenerator Enhancements
- New _extract_content_instruction_from_heading_schema method for instruction parsing
- Enhanced _get_placeholder_content method with schema-aware content generation
- Updated method signatures to support schema_file_path parameter throughout
- Robust handling of both content instruction and legacy schema formats

### CLI Integration
- Updated generate-stub command documentation with content instruction examples
- Enhanced help text explaining automatic content instruction usage
- Fixed output file generation to include schema references correctly
- Maintained full backward compatibility with existing usage patterns

### Technical Implementation
- Schema reference comments (<!-- Generated from schema: path -->) in generated drafts
- Content instruction text extracted from x-markitect-content-instructions fields
- Support for all instruction types (description, example, constraint, template)
- Integration with existing heading hierarchy and placeholder style systems

## Integration and Compatibility:
- Seamless integration with Issue #54 content field instructions
- Full backward compatibility with existing schemas and usage
- Works with outline mode schemas and heading text capture features
- Comprehensive error handling and graceful degradation

## Testing and Validation:
- Comprehensive test suite covering all acceptance criteria
- Integration tests with schema-generate → generate-stub workflow
- Validation of schema reference metadata and content instruction usage
- Backward compatibility testing with legacy schemas

This completes Issue #55 with full feature implementation, comprehensive testing,
and enhanced documentation for schema-based draft generation capabilities.

When a schema contains x-markitect-content-instructions-enabled: true,

schemas created using the --include-content-instructions option.

Generated stubs include a comment referencing the source schema file
