pub async fn run_from_yaml_str(yaml: &str) -> CliResult<RunSummary>Expand description
Convenience entry point for integration tests and custom hosts: parse a YAML config string, expand the matrix, and run all rows.
This skips the install_observability call that commands::run::run
performs — callers can wire their own metrics recorder / tracing
subscriber before calling this function (or not at all).
