Pull request overview

This PR ensures device-instruction requests are registered even when failures occur early in handle_device_instructions, so the system can still emit a deterministic “running → error” resolution sequence.

Changes:

• Add _ensure_request_registered() to register a placeholder request for early-failure paths.
• Call _ensure_request_registered() in exception handlers before set_finished() to guarantee resolution.
• Update the disabled-device test to assert actual outbound response messages via connector.send.
