formatDurationPrecise bucketed durations on the raw ms value but only rounded at display time, so inputs just below a unit boundary carried into the next unit without re-bucketing (e.g. 59999ms -> "60.00s"). Round to centisecond precision FIRST, then decompose in integer centisecond space so the seconds component stays in [0.00, 59.99] and carries re-bucket into the next unit (59999ms -> "1m 0.00s").

Reuse the existing MS_IN_* constants instead of the centisecond decomposition; behavior is unchanged. Co-authored-by: Cursor <cursoragent@cursor.com>

Summary
The events list and new-trace-viewer timeline bar labels were rounding durations to whole seconds (e.g. 1.63s → "2s"). They now use a new locale-aware
formatDurationPrecisethat never snaps to whole seconds and shows two-decimal seconds above 1s. Sub-second values show whole ms; ≥1m decomposes into d/h/m with two-decimal seconds. The gap delta label still uses the compactformatDuration.Test plan
