Every Monday morning .github/workflows/weekly-release.yml tags the newest green
commit on main as v<VERSION>, publishes a GitHub Release from the CHANGELOG
headlines and fast-forwards refs/heads/stable to it (scripts/release-cut.ts;
workflow_dispatch with dry_run, and ref for a hotfix). Team-mode installs
follow stable through the new update_channel key (auto: stable when
team_mode, else main) in bin/gstack-session-update, bin/gstack-update-check,
bin/gstack-upgrade and /gstack-upgrade. Per-merge stamping and the merge
train are unchanged. docs/releases.md explains it.
