Emir Beganovic 0abcbb0b97 Nightly: its decisions are scripts, with tests
Which channels a run makes and where they go, and what is laid out and
what latest.json then says, were shell inside the workflow file, tried
only by hand. A green run published a latest.json with the Omarchy
version in it twice, and nothing noticed.

Both are scripts now, test/vm-image/nightly-plan and nightly-layout,
and test/unit/nightly-test.sh tries them without a runner: a first run,
a run started again, a release already published, a tag that is not a
version; every field of latest.json for each channel, the checksums
against the files, the version a consumer reads from the ISO's name.
nightly-layout also refuses to describe an image it cannot describe
fully, and checks its own latest.json before anything is published.

The same test covers two things the install test decides: which Omarchy
packages an ISO installs, and when an install is over.

# Says which channels a nightly run makes, under which version, and where
# each one is published. It decides; the workflow fetches what it needs to
# know and passes it in, so every case can be tried without a runner.
#
# nightly-plan <date> <run_number> <run_attempt> <event> <release_tag> [published_stable]
#
# date today, as YYYY.MM.DD
# event what started the run: schedule, workflow_dispatch
# release_tag omacom/omarchy's latest release, such as v4.0.4
# published_stable the version stable/latest.json names now, if any
#
# Prints a JSON list of {channel, version, release}; release is the path
# under the site.
#
# An edge version is the date and the run number. A stable version is the
# release's own, and on a scheduled run a release already published is left
# out: it is done once. Two builds are never the same bytes and a published
# file is never replaced, so no path is used twice: a stable image has the run
# number in its path, and a run started again adds its attempt to the number.
