v0.42.0

Report time transparency: (1) each scenario's DURATION now breaks down into a reconciling bar — setup · deps · plan · nav · actions — where nav isolates the goto + page load/hydration before the first action (the real SPA time sink); (2) the suite header shows wall-clock (real elapsed) instead of the sum of per-scenario totals, which inflated ~Nx under --concurrency N. No performance change — the numbers just add up now.
