docs(pi): stop describing Babysit's digest check in the present tense

Three comments still read as statements of current behavior: the Create PR push
test's note beside the assertion that proves no verification happens, github-pr's
module doc naming a second consumer that does not exist yet, and the timeout
floor claiming a short-lifetime run was doomed regardless when the reserved
ceilings are pessimistic enough that it may well finish.
