/**
 * Resolve the active context for a CLI invocation.
 *
 * Canonical schema is `{ currentContext, contexts }` (written by
 * `omniroute contexts ...`). For backward compatibility we also read the legacy
 * `{ activeProfile, profiles }` shape and a bare top-level `baseUrl` — older
 * configs and `api.mjs::getBaseUrl` used those before remote-mode unified the
 * store. `overrideName` (from `--context`/`OMNIROUTE_CONTEXT`) wins when set.
 *
 * A context may carry `{ baseUrl, accessToken?, apiKey?, scope?, description? }`.
 * `accessToken` is the scoped CLI access token (preferred); `apiKey` is the
 * legacy inference key kept for back-compat.
