/**
 * WebUI static server.
 *
 * Serves out/renderer/ as the SPA, proxies /api/* and /ws to the backend,
 * and handles /api/auth/login + /api/auth/logout locally via web-host auth.
 *
 * Design: Node native http + serve-handler. No Express. No business routes
 * beyond the login pair — those ALL live in aionui-backend.

/**
 * M5 equivalence test: legacy webserver vs. web-host static-server.
 *
 * Boots both servers on two local ports against the SAME mock backend, then
 * issues the 10 canonical requests from the M5 requirements and asserts
 * that status / body-shape / critical headers match (within the documented
 * deltas — see `KNOWN_DELTAS` below).
 *
 * Why live here (not in packages/web-host/tests/): web-host MUST NOT import
 * packages/desktop; legacy webserver MUST NOT be re-used in web-host. The
 * desktop test project has the right alias coverage for both sides.

- 关键提醒:
  * WebUIConfig schema 在 M5 冻结(含 passwordHash / adminUsername /

  * 老 webserver 未切换,桌面 GUI 开关 / --webui 仍走老代码
  * 等价性 10/10 对比通过(细节见 handoff 表)
  * 决策 D-01 / D-02 已实现,M6 切换前必读
