/**
 * ConnectionInvocationResult content type for ConvosConnections (device →
 * agent write outcomes).
 *
 * Mirrors the iOS `ConnectionInvocationResultCodec` (PR #767):
 * - Content type: convos.org/connection_invocation_result:1.0
 * - Payload: JSON-encoded `ConnectionInvocationResult`
 * - Fallback: `"<actionName>: <status>"`
 * - shouldPush: false
 *
 * Always emitted by the device, even on failure. `invocationId` echoes
 * the request so the agent can correlate.
