// opencode plugin — the Intake interviewer's propose_draft tool, on Grok.
//
// Parity with the Claude Intake's SDK tool (roboco.agent_sdk.intake_driver
// .build_intake_options): the model calls propose_draft once the task spec is
// ready, and the driver (OpencodeServeSession.normalize_opencode_message ->
// _is_propose_draft -> _draft_from_tool_input) turns that tool call into the
// `draft` chunk the panel renders as the reviewable draft card.
//
// Without this, propose_draft is a tool the prompter prompt tells the model to
// call but that does not exist on Grok, so no draft card ever appears and the
// human can't launch a task from a Grok intake chat. The execute() only ACKs —
// the payload that matters is the tool-CALL input, which the driver intercepts.
//
// Loaded ONLY into the roboco-agent-grok-prompter image via
// ROBOCO_OPENCODE_EXTRA_PLUGINS (the one-shot delivery roles never draft).
//
// UNVERIFIED-LIVE: opencode's exact tool-call Part shape in the synchronous
// serve reply — confirm a Grok intake spec yields a draft chunk -> panel card
// on the NAS before relying on Grok intake.
