/**
* The in-process SPAWN subagent backend: registers a {@link SubagentProvider}
* on `ctx.subagents` that runs each child as a FRESH child {@link Agent} on the
* same cordis context (its own session, own system prompt, zero parent
* context). The cheapest transport, reusing the agent factory's quiescent
* teardown.
*
* The run mechanics live in `@deepseek-ai/dsh-subagent-inprocess`
* ({@link startInProcessRun}); this backend just passes NO seed (a fresh
* child). The fork backend is an independent peer over the same driver.
*
* Structured output (`outputSchema`) is supported through the driver's
* per-child scoped runtime: the child registers its real-schema capture tool,
* prompt instruction, and enforcement listeners inside the creation setup
* window, and its scope owns their lifetime.
*
* Plugin export shape: named `name`/`inject`/`Config`/`apply`, NO default.
