// Docker self-update endpoint behavior.
//
// User report (2026-04-29): "为什么docker不支持更新 支持呗。。。" — i.e.,
// the dashboard's existing self-update path bails on docker
// deployments with a hint to run `docker compose pull && up -d`
// manually. v2.0.41 wires an opt-in path that uses /var/run/docker.sock
// + a one-shot deployer sidecar to recreate the container in-place.
//
// We can't actually exercise the docker daemon in unit tests (no
// socket on Windows / CI runners), so static-validate the module
// shape and the api.js wiring.

// User report (2026-05-01): one-click 「更新并重启」on a host that has
// never pulled `docker:24-cli` failed with the dashboard surfacing
//   ✗ Failed to execute 'querySelector' on 'Document': '[data-i18n=
//     "error.docker API POST /containers/create -> 404: {"message":
//     "No such image: docker:24-cli"} "]' is not a valid selector.
//
// Three compounding bugs:
//
//   1. runDockerSelfUpdate only pulled ctx.image (the windsurf-api
//      image) — never pulled DEPLOYER_IMAGE. Fresh hosts hit
//      `/containers/create -> 404 No such image: docker:24-cli`.
//
//   2. The dashboard's applyUpdate() picked `r.detail || r.reason`
//      when constructing the user message, so the long raw error
//      string ("docker API POST /containers/create -> 404: ...") won
//      over the short stable code ("deployer-create-failed"). The long
//      string then went into translateError -> I18n.t -> querySelector
//      and exploded.
//
//   3. I18n.t's zh-CN fallback path did `document.querySelector(
//      '[data-i18n="${key}"]')` with no escaping, so any key containing
//      `"` / `{` / `:` threw DOMException and broke the resolver.
