Module headless 

2026-09-26: Driving a benchmark without a terminal: start it on the executor, drain its messages until it finishes, build the run record and save it with crate::history::save, as the dashboard also does.

Owner: bench. Invariants:

• run_blocking validates the parameters before the executor starts.
• A run that ends without a terminal frame is recorded as a failure.
