Reload no longer crashes on Chain.UNSPECIFIED, removes gRPC upstreams
by prefixed id with lifecycle cleanup, applies methods.disabled changes
synchronously, pushes status via existing SubscribeChainStatus streams,
and optionally closes client RPCs so edges reconnect. NativeCall returns
-32601 (CODE_METHOD_NOT_EXIST) for disabled/unknown methods.
