Do not consider PR at all if any of workflows is still running

I think we might have overlapped with execution while workflow was still running so we did not get any logs . and that run eventually actually timed out at 6 h.

```shell
dandi@drogon:/mnt/backup/dandi/tinuous-logs/dandi-archive/2025/12$ cat './01/github/pr/2644/01bfb52/Test Integration with dandi-cli/4577/test (3.13, master)/system.txt'

dandi@drogon:/mnt/backup/dandi/tinuous-logs/dandi-archive/2025/12$ git -C './01/github/pr/2644/01bfb52/Test Integration with dandi-cli/4577/test (3.13, master)/' log . | head
