`check.yml` ran only on push to `main` and on pull requests against `main`. Every unit is a PR based on `next`, and `next` is pushed on each squash-merge, so no unit PR and no push to `next` ever ran CI; a broken `next` would first surface on the milestone PR. `next` is added to both branch lists; nothing else in the workflow changes. The README Entrypoints section now says where CI runs.
Disclosure: the CI run on the PR itself fired (the proof the trigger works) but was red because the runner had no disk space left before any check step ran; the local gate was green.

`--cron` sets the UI quiet, but `Warningf` and `Errorf` are unconditional, and the snapshot summary is routed through `Warningf` on purpose so cron delivers something on a successful run. The help string said `silent unless error`, so a user could read normal cron output as a failure. It now says `silent unless warning or error`, matching the README. String only; no behavior change.
