feat: Add Handlebars helpers and utility classes for TOSCA export

- Implemented HandlebarsHelperRegistry to register helpers for TOSCA file generation.
- Created ExportErrorHandler for centralized error handling during export operations.
- Developed ImportCollector to manage import statements for TOSCA files.
- Introduced NodeTemplateCollector for collecting and filtering node templates.
- Added PropertyResolver to resolve TOSCA property values from model elements.
- Built PropertyTreeBuilder to construct YAML property trees from model elements.
- Created StereotypeHelper for checking stereotype applications in model elements.
- Developed TemplateClassifier to classify templates and parameters.
- Added TemplateConstants for defining template names and paths.
- Implemented TemplateConverter for converting objects to specific TOSCA types.
- Created YamlFormatter for formatting values into YAML scalar syntax.
