fix(ci): #540 landing review follow-up

Move the nightly browser-suite cron from 03:23 to 03:29 UTC, authored as
Ark0N. GitHub sends scheduled-run failure notices to whoever last modified
the cron line, but its docs do not say whether that means the commit author
or the pusher. The previous cron edit (02c65e98) was authored under the
maintainer identity, whose noreply@anthropic.com address GitHub resolves to
the unrelated login "claude", so under the author reading the nightly's
failure notices would never reach the maintainer. With this commit the
author, the committer and the pusher are all Ark0N, so every reading lands
on the maintainer. Only the minute changes; no doc or test names a clock
time.

After the first scheduled run on master, confirm with
gh api 'repos/Ark0N/Codeman/actions/runs?event=schedule&per_page=1'
--jq '.workflow_runs[0].actor.login', which should print Ark0N.
