Sent by the side that decoded callback facades to tell the owner it no longer
holds those facades, so the owner can drop the matching entries from its
callback registry. Releases are best-effort and fire-and-forget: a peer that
does not understand this message simply ignores it, and a late invocation of a
released callback is dropped rather than delivered.
