This doesn't yet integrate spans and trace IDs

• The parameter name 'logg' is ambiguous and inconsistent with typical naming conventions. It should be renamed to 'logger' to match the field name '_logger'.

The structured logging syntax is incorrect. The '@' symbol should be used without string interpolation. Change to '_logger.LogInformation("Starting delay: {Duration}", duration);' for proper structured logging.

Suggested change

	_logger.LogInformation($"Starting delay: {@duration}");
	_logger.LogInformation("Starting delay: {Duration}", duration);

The structured logging syntax is incorrect. The '@' symbol should be used without string interpolation. Change to '_logger.LogInformation("Creating child workflow {Name}", name);' for proper structured logging.

Suggested change

	_logger.LogInformation($"Creating child workflow {@name}");
	_logger.LogInformation("Creating child workflow {@Name}", name);

Whats the purpose of changing the syntax here? I feel as though both are readable as each other
