Expand description

Write a metadata-only record for a stamped message: presence tag = 0u8 (no payload), followed by tov and metadata. Wire-compatible with the existing decode path — a reader sees payload: None for the frame, same as if the source had been disabled entirely, but the surrounding timestamp/status are preserved.

Codegen emits a call to this helper when a slot’s producing task is configured with HandleContent::None or HandleContent::TouchedOnly and the handle wasn’t touched.
