ci(all-green): print per-upload timing summary

The three uploads run as backgrounded subshells so their log lines
interleave, making it impossible to tell which one is slow from the raw
log. Wrap each in run_timed to record its own wall-clock time to a shared
file, printed as a summary once they've all finished.
