Speed history by the hour and by the day

Each listed operation's hourly and daily p50, p95 and p99 (Runtime's own time, the network's part and the total), sample count and failure count are now kept indefinitely and returned by https://status.withruntime.com/speed/history.json?op=<id>&step=hour|day&from=&to=. from and to take a date (2026-11-03) or an ISO 8601 time and are rounded down to the step; by default a request returns the last 48 hours, or the last 365 days with step=day. A request returns at most 744 hourly or 3,660 daily points, and returns 400 for an unknown operation or an invalid range. Percentiles are computed from each hour's or day's own samples. Responses are cached for one minute (speed).
