Subject: [PATCH] ci: trigger auto-build to verify push trigger works
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

empty commit, no code changes. 用于验证 build-image.yml 的 push trigger
确实在 commit 推送后自动跑起来，不需要去 Actions UI 手动点。

如果这次 push 后 Gitea Actions 没有自动出现新 run，说明 paths-ignore
对 empty commit 的过滤行为是"vacuously skip"，需要至少一个非 ignore 路径
的真实改动才能触发。
