# 版本标签 v* → 测包、发 PyPI、建 GitHub Release，再级联：
#   - Sync Main Into Develop
#   - Build Octop FPK（复用本 Release 的 wheel；等待 docker-publish 的多架构 GHCR 镜像）
#
# 与 docker-publish.yml / octop-desktop.yml 并行（由 Auto Tag 同时 dispatch，
# 或人工 push v* tag 同时触发）。wheel / sdist 只发 PyPI 和 GitHub Release。
# 桌面安装包与 FnOS FPK 挂到同一 GitHub Release 后，再上传到同一个 COS 版本目录。
