# Every Tuesday 09:00 Asia/Shanghai, cut the next minor release branch from main HEAD:
#   1. Compute version (highest release/vX.Y.Z -> bump minor -> X.(Y+1).0; e.g. 0.11.0 -> 0.12.0)
#   2. Create release/vX.Y.Z, bump apps/packaged/package.json, push
#   3. Create the "backport release/vX.Y.Z" label
# The push uses the App token (not GITHUB_TOKEN), so it triggers notify-release-feishu
# -> builds a nightly package and posts the Feishu card.
