sendRaw

Sends a raw ToRadio frame to the device.

This is a low-level escape hatch for device features not yet covered by higher-level APIs (e.g., MQTT client proxy messages, XModem file transfers). The SDK engine does not track or acknowledge these frames — delivery is best-effort at the transport level.

Prefer send, sendText, or the typed sub-APIs (admin, telemetry, routing, storeForward, etc.) whenever possible.
