// Print Job Operations - All Stubs

// Orchestrates the cloud print workflow: upload the sliced G-code straight to R2
// via a presigned URL (upload_gcode_via_cloud), then finalize over HTTP
// (start_cloud_print_job). The finalize call is what actually gets the file to
// the printer: the gateway HEAD-verifies the R2 object, then relays
// print.project_file to OrcaSonar over the gateway's OWN cloud relay connection -
// not this agent's MQTT session. See CLOUD_PRINT_JOB_MQTT_DESIGN.md for the
// MQTT-native alternative (publishing print.project_file directly over this
// agent's own cloud connection) and why it isn't used yet.
//
// This deliberately does NOT go through start_sdcard_print/print.gcode_file:
// that command is the generic "start this file already on the printer" primitive
// (also used by the LAN start_local_print path, and meant to stay that way as it
// grows params like filament mapping), and has no download-awareness to give it.
