# 发布流水线：release/** 分支推送即发版。
#
# 设计依据 docs/git-branching.md §七（发版产物清单）与 git-release-discipline
# skill。核心事实：**推 tag ≠ 完成发版** —— 完整发版是四件事：
# bump meta.Version → 打 tag → 打包产物 → 建 release 条目并上传附件。
# （v1.3.1–v1.3.6 曾只推了 tag，产物与 release 条目全缺，事后补做。）
#
# 版本号来源：internal/meta/meta.go 的 Version（唯一事实源）。
# 所以发版动作 = 在 release/vX.Y.x 上把 meta.Version 改成目标版本后推送。
# 版本未变的推送（如改文档）会因 tag 已存在而**整轮跳过**，不会重复发版。
