test: remove fixed child-process deadlines from tests

239 literal timeoutMs values on cli.run and processes.run only restated
a guess at host speed. On hosted runners with four workers, cliOutput's
3-second value failed while the command still produced correct output.
Deadlines that are the behavior under test, derived from an operation
budget, or that bound a regression's wait remain.
