The stderr-progress idle-timeout test used a 0.1s idle window with 0.04s
ticks — shorter than Windows process spawn, so the first chunk could never
arrive in time (deterministic failure on Windows, flake under Linux CI
load). Verified failing identically on pristine main before the change.
Fix: emit the first tick immediately, tick every 50ms for ~400ms total,
250ms idle window (5x tick period). The pass still depends on the progress
extension while tolerating real spawn/scheduling latency.
