Summary: this change removes the dependency on hyperactor_multiprocess from the monarch_hyperactor crate with the smallest possible surface-area change. - remove hyperactor_multiprocess from BUCK and Cargo.toml so the python bindings no longer depend on the multiprocess/system-actor stack. - delete python-facing helpers that were thin wrappers over the system actor and proc supervision path: - `PyActor.world_status` - `PyProc.world_status` - `check_actor_supervision_state` and the periodic controller health check - replace the multiprocess-based proc bootstrap in `init_proc` with `unimplemented!()`, so the symbol still exists but no longer wires a `Proc` into the old system-actor supervision model. the intent here is just to decouple monarch_hyperactor from hyperactor_multiprocess; no new bootstrap or supervision path is introduced. any remaining callers that depend on `init_proc` or `world_status` will now hit `unimplemented!()` at runtime and should be migrated to the newer mesh/host/proc bootstrap APIs in subsequent stacks.
