Three commands, all host-independent so the browser build answers them from
the same model layer as the desktop:
- models_snapshot_request, for the edit-session boundaries only the frontend
can see. It takes a reason and nothing else — the caller does not decide
whether anything changed, because content addressing already has.
- models_request_version, which returns a version and the live request's
content together so they are guaranteed comparable, plus the same
content-hash verdict the backend uses rather than a second opinion formed in
TypeScript.
- models_restore_request_version.
The browser host also snapshots before its own send, since its send pipeline
is in TypeScript rather than in the shared crate.
Bindings regenerated with CI's `cargo test --all --features
yaak-app-client/wry`, which also drops a stale ImportSourceResource from the
rpc-schema copy and adds a missing ImportSource to the plugins copy.
