The base-version derivation used `git describe --match v1.14.0-alpha.*` as the
primary source, but actions/checkout only fetches THIS repo's tags — the alpha
tags are SagerNet/sing-box (upstream) tags, absent in the CI clone. So `git
describe` found nothing and silently fell to the subject-grep fallback, which
resolves alpha.36 (alpha.37 was merged in a commit whose subject omits the
number). That's why rc.17/rc.18 notes shipped "base alpha.36" while a local
clone with upstream tags gets 37.
Fetch just the upstream v1.14.0-alpha.* tags before git describe so the primary
graph-based path works in CI. Both hand-fixed on the published releases; this
makes the next tag correct automatically.
