	def ensure_installed(tool: str, version: Optional[str] = None) -> str:
	"""Ensure a tool is installed, resolving its version if necessary."""
	LOG.info("Ensuring %s is installed", tool)
	tool_path = _resolve_install(tool, version)
	if tool_path:
	LOG.info("%s available at %s", tool, tool_path)
	return tool
	LOG.warning("%s not found and could not be installed", tool)
	return tool

It might have a chance to review and refactor ensure_installed to make it more straightforward
