// Nit-2 handoff (.malvin/incomplete_handoff_pi_sdk_nit_polish.md): explicit
// lifecycle proof for the real embedded runtime. The mock-env client tests
// cannot observe the thread (fake_embedded_session has runtime: None), so
// this test drives PiRuntime directly.
//
// Determinism: PiRuntime::start returns only after the worker sends ready,
// and the worker then blocks on cmd_rx.recv(), so the named thread
// necessarily exists when start() returns Ok. shutdown() joins the thread
// before returning; we assert join() success rather than scanning /proc
// afterwards, because Linux child threads inherit the parent's comm name.
//
// Offline: provider/model/api_key construction performs local work only;
// network I/O happens at prompt time, which this test never issues. Same
// shape as the published crate's hermetic create_agent_session tests.
//
// HOME is redirected to a tempdir so Config/AuthStorage loads never touch
// production config (VISION.md).
