More prep-to-reduce the `Actor` method-iface

- drop the (never/un)used `.get_chans()`.
- add #TODO for factoring many methods into a new `.rpc`-subsys/pkg
  primitive, like an `RPCMngr/Server` type eventually.
- add todo to maybe mv `.get_parent()` elsewhere?
- move masked `._hard_mofo_kill()` to bottom.
