Research direction

Start by reading the blobmsg_add_u64() definition and tracing its call to blobmsg_add_field(). Determine whether the signed treatment is intentional or needs clarification in the project documentation. Done means providing a clear explanation of the uint64_t parameter and BLOBMSG_TYPE_INT64 behavior, with any relevant documentation updated.
