Devcontainer started failing upon codespaces creation

Sync my local copy with `main`. When I open a codespace using the `konductor` devcontainer, I get booted into a recovery container due to a failed devcontainer build.

从链接的完整日志和在创建 Codespaces 期间使用的 konductor devcontainer 开始，然后检查导致构建失败的配置。重现该失败，并验证 devcontainer 能够成功构建并打开 Codespace，而不会回退到 recovery。
