/**
* @deepseek-ai/dsh-host-apiproxy — the API gateway every client shape shares:
* the ApiProxy contract (api/: types + zod schemas, browser-safe), the fetch
* carrier pair (fetch/: toFetchHandler on the host side, AbstractApiClient +
* platform subclasses on the client side), and the host-side implementation
* (api-proxy.ts: createApiProxy + the ApiProxyService gateway plugin providing
* `ctx.apiProxy`). Transport-agnostic by design: this package registers no
* routes — physical carriers wrap `ctx.apiProxy` themselves.
*
* The gateway consumes `ctx.agentDefaultModel` only for the deployment metadata
* returned by `host.describe`; Session Controller owns Session model selection.
