 * Harness factories. Each returns a thin `Harness` value: an id plus how to invoke it one-shot

 *
 * NOTE — the one-shot invocation forms below (`opencode run <prompt>`, `codex exec <prompt>`,
 * `claude -p <prompt>`) are the expected headless shapes but are PENDING live verification against
 * the baked workspace image (see the SDK plan's task #2, "verify harness one-shot CLI semantics").
 * Until that is confirmed, only `opencode()` is exercised end-to-end; the others are provided for the
 * typed surface and adjusted once verified.
