* Point every Cursor SDK state surface at writable tmpfs and return the * `stateRoot` to pass to `Agent.prompt`: * * - `platform.stateRoot` covers the SDK's in-process run/checkpoint stores * (the `sdk-agent-store` path that failed in production). * - `HOME` / `CURSOR_CONFIG_DIR` / `CURSOR_DA

()

 * invocations in a shared instance can't observe a mix.
