/**
 * Official China-mirror env vars (WS-A1a). Single source of truth: the constant
 * map that points dependency pulls (npm/pip/uv) at official mainland mirrors —
 * NOT our OSS. Lives in the config layer (not infra) so it can be public API:
 * the runtime gateway merges it into the agent env when the user's region/network
 * switch is on (cross-cutting ③); MCP subprocesses and skill shells then inherit
 * it via the agent-process FORWARDED_ENV_KEYS list.
 *
 * Honest scope: this only redirects dependency *resolution* to official mirrors
 * (covers most). It does NOT guarantee cold/new packages (npmmirror sync lag →
 * 404) or run-time foreign APIs — those are surfaced as reachability notices (WS-A6).
