Module manifest 

The narrow backend-manifest constructor shared by host-registered table backends.

Table backend crates (sim-table-hash, sim-table-lazy, …) each declared a byte-identical empty LibManifest: no exports, no requirements, no capabilities, HostRegistered, ABI {0, 1}. Backend registration itself (the has-lib guard and register call) stays in each crate because the registry differs; only the manifest shape is shared here.

Functions

backend_manifest

Build the empty, host-registered LibManifest a table backend presents.
