feat: Implement Issue #54 - Add content field instruction capabilities

Browse Source 
This implementation adds comprehensive support for content field instructions
that provide guidance for document generation from schemas.

## Key Features Added:

### CLI Options
- `--include-content-instructions` flag to enable content instruction fields
- `--instruction-type` parameter with options: description, example, constraint, template
- Full integration with existing outline mode and heading text capture features

### Schema Generation Enhancements
- Content instruction fields (x-markitect-content-instructions) with contextual guidance text
- Instruction type metadata (x-markitect-instruction-type) for type specification
- Metaschema extension (x-markitect-content-instructions-enabled) for feature detection
- Support for headings, paragraphs, and lists content instructions

### Error Handling
- InvalidInstructionTypeError for robust validation of instruction type parameters
- Comprehensive input validation with clear error messages

### Integration and Compatibility
- Seamless integration with outline mode and heading text capture
- Full backward compatibility - existing behavior unchanged when feature disabled
- Works with all existing CLI options and modes

### Documentation
- Updated CLI help with examples and detailed feature descriptions
- Clear documentation of all instruction types and their purposes

## Technical Implementation:
- Enhanced SchemaGenerator with content instruction generation logic
- Added `_generate_content_instruction` method for contextual instruction text
- Extended schema structure to include instruction metadata
- Maintained clean separation of concerns and existing code patterns

## Testing and Validation:
- Comprehensive test coverage following TDD8 methodology
- All existing functionality preserved and tested
- Integration tests for all feature combinations
- Error handling and edge case validation

This completes Issue #54 with full feature implementation, documentation,
and comprehensive testing coverage.
