}Submit a durable async task to this mesh node. Returns a task_id; poll nexus_task_status or supply callback_url for push delivery. Every finished task issues an Ed25519-signed, hash-chained receipt.

| vector_data | any | engine-specific payload (object or JSON string) |
| callback_url | string | public HTTPS URL invoked with the signed result on finish |

| peer* | string | peer node_id or endpoint URL |
| vector_data | any | inner payload for the peer (object or JSON string) |
| vector_type | string | task type the peer understands |
| callback_url | string | public HTTPS URL for the signed result |
| payload_value | number | declared task value |
