Add total run time to summary.json and HTML report

AnHeuermann · claude · AnHeuermann · commit b894f8467271 · 2026-02-26T11:47:08.000+01:00
Track wall-clock duration of the full test run in RunInfo.total_time_s.
The value is written to summary.json and displayed in the HTML report
as a human-readable string (e.g. "3 min 12 s").
