// opencode plugin — the Intake interviewer's propose_draft tool, on Grok.
//
// The model calls propose_draft once the task spec is ready; this delivers the
// draft to the panel's reviewable draft card.
//
// WHY IT POSTS DIRECTLY (not via the driver): opencode's synchronous serve reply
// (POST /session/:id/message) returns only the final assistant text + step
// markers — NOT the tool-CALL parts. So OpencodeServeSession cannot intercept
// this call to emit a `draft` chunk (verified live: a propose_draft call comes
// back as parts=[step-start, text, step-finish], no tool part). Instead the tool
// POSTs the draft straight to the prompter-live relay — the same
// /api/prompter/live/{session}/events endpoint the driver's relay sink uses — so
// the panel renders the card regardless. (The Claude intake path differs: the
// Claude SDK DOES expose the tool-use block, so its driver intercepts it.)
//
// Loaded from the plugin auto-discovery dir (~/.config/opencode/plugin/), baked
// into the grok-prompter image only (the one-shot delivery roles never draft).
// The container provides ROBOCO_API_URL + ROBOCO_PROMPTER_SESSION_ID.
