Pull Request Overview

Implements DDS data publication by extending the enabler API, refactoring callbacks into a CallbackSet, and updating tests and examples to cover topic notifications and sample publishing.

• Introduce CallbackSet and update create_dds_enabler signatures to accept it
• Add DDSEnabler::publish method and wire up publication in runner and examples
• Update tests to assert on received topics and comment out a large block of optional typed tests

• In write_yaml_file there is no buffer declared, leading to an undefined identifier. You need to declare and populate a buffer (similar to write_json_file) or write Template directly.

outFile << buffer;

• [nitpick] The variable name Template conflicts with the C++ keyword and general naming conventions. Consider renaming it to yamlTemplate or similar.

std::string Template =

• The new publish() API is not covered by any unit tests—consider adding tests to validate JSON publishing and error paths.

• [nitpick] Brace placement style changed here (opening brace on new line) but other sites in this file use the same-line style. Align with the project's coding style for consistency.
