/**
 * A task that sends an interaction to a human via an IHumanConnector.
 *
 * Supports four interaction kinds:
 * - "notify": Send a notification (fire-and-forget, task completes immediately)
 * - "display": Present content to the human (charts, data, markdown)
 * - "elicit": Request structured input via a form (MCP elicitation model)
 * - "confirm": Ask a human to approve or refuse one described action
 *
 * The contentSchema describes WHAT to render. The kind determines HOW.
 * For "elicit", the output includes the human's submitted data.
 * For "notify"/"display", the output is just `{ action: "accept" }`.
