Merge branch 'main' into fix/cd-push-trigger-yaml

根因：deploy.yml notify-deploy-success job 中 python3 -c 使用多行字符串，
Python 代码零缩进（column 0）破坏了 YAML literal block scalar (run: |)，
导致 Gitea YAML 解析器报错 'line 114: could not find expected :',
在 DetectWorkflows 阶段被静默丢弃，push 事件无法触发 deploy。

Gitea 日志证据：
  ignore invalid workflow "deploy.yml": yaml: line 114: could not find expected ':'

修复：将多行 python3 -c 改为单行，避免零缩进代码行破坏 YAML 块结构。

影响范围：仅 deploy.yml，不影响 ci.yml 和 e2e.yml
验证方式：YAML 解析已通过，合并后观察 push 事件是否触发 Actions
