silverwind dcba546cb3 fix: align process handling and fix Windows crashes (#1376) ...

The intermittent Windows test crashes came from step errors formatting a nil `rc.Run`. `fmt` recovers the nil dereference, but on CPUs with AMX the recovered fault overflows into the heap (https://github.com/golang/go/issues/81238). The errors now name the job, and the Windows test VM hides AMX and runs on UTC, so cached boots no longer jump back 8 hours mid-test.

Windows commands now start suspended and resume once they are in their job objects, so no child escapes them. That drops the process scan reading other processes' memory and the last `unsafe` code, which `depguard` now denies. Step processes outlive a crashed runner, and commands are no longer looked up in the runner's working directory, both as with GitHub's runner.

Like GitHub's runner, host jobs on Linux and macOS now end the processes carrying the job's `RUNNER_TRACKING_ID`, and image pulls and Dockerfile action builds are retried.
