Tyler Goodlet cd4fd02e5c Official service-mngr to `tractor.hilevel` move
Such that we maintain that subsys in the actor-runtime repo (with
hopefully an extensive test suite XD).

Port deats,
- rewrite `open_service_mngr()` as a thin wrapper that delegates into
  the new `tractor.hilevel.open_service_mngr()` but with maintenance of
  the `Services` class-singleton for now.
- port `.service._daemon` usage to the new
  `ServiceMngr.start_service_ctx()` a rename from
  `.start_service_task()` which is now likely destined for the soon
  supported `tractor.trionics.TaskMngr` nursery extension.
- ref the new `ServiceMngr.an: ActorNursery` instance var name.

Other,
- always enable the `tractor.pause_from_sync()` support via `greenback`
  whenever `debug_mode` is set at `pikerd` init.

Tyler Goodlet 4d29722794 More service-mngr clarity notes
Nothing changing functionally here just adding more `tractor`
operational notes, tips for debug tooling and typing fixes B)

Of particular note is adding further details about the reason we do not
need to call `Context.cancel()` inside the `finally:` block of
`.open_context_in_task()` thanks to `tractor`'s new and improved
inter-actor cancellation semantics Bo

Tyler Goodlet 77703f2201 Drop `.cancel_actor()` from `maybe_spawn_daemon()`
Since `tractor`'s new and improved inter-actor cancellation semantics
are much more pedantic, AND bc we use the `ServiceMngr` for spawning
service actors on-demand, the caller of `maybe_spawn_daemon()` should
NEVER conduct a so called "out of band" `Actor`-runtime cancel request
since this is precisely the job of our `ServiceMngr` XD

Add a super in depth note explaining the underlying issue and adding
a todo list of how we should prolly augment `tractor` to make such cases
easier to grok and fix in the future!
