Deterministically release a decoded callback facade.
Mirrors releaseProxy from kkrpc/remote-refs: it tells the owning channel to
drop the callback's registry entry and marks the local facade unusable. This is
idempotent and safe on non-facade values (returns false). On runtimes without
FinalizationRegistry it is the only way to free the owner-side entry, since
automatic collection is unavailable there.
