/**
 * HTTP wrapper for the ServiceNow ProcessFlow REST API (`/api/now/processflow/`).
 *
 * Provides typed GET and POST methods with path interpolation for operations
 * such as retrieving flow definitions, testing flows, and other Flow Designer
 * REST interactions.
 *
 * Usage:
 * ```ts
 * const pfr = new ProcessFlowRequest(instance);
 * const def = await pfr.get<FlowDefResponse>('flow/{flow_sys_id}', { flow_sys_id: id }, queryParams);
 * const res = await pfr.post<TestResponse>('flow/{flow_sys_id}/test', { flow_sys_id: id }, queryParams, body);
 * ```
 *
 * Note: The `as ServiceNowInstance` cast in `_doRequest` mirrors the pattern
 * used by TableAPIRequest. The root fix (accepting IServiceNowInstance in
 * ServiceNowRequest's constructor) is a broader refactor tracked separately.
