Tyler Goodlet 1f1a3f19d5 Fix multi-daemon debug test `break` signal..
It was expecting `AssertionError` as a proceed-in-test signal (by
breaking from a continue loop), but `in_prompt_msg(raise_on_err=True)`
was changed to raise `ValueError`; so instead just use as a predicate
for the `break`.

Also rework `in_prompt_msg()` to accept the `child: BaseSpawn` as input
instead of `before: str` remove the casting boilerplate, and adjust all
usage to match.

Tyler Goodlet a628eabb30 Officially test proto-ed `stackscope` integration
By re-purposing our `pexpect`-based console matching with a new
`debugging/shield_hang_in_sub.py` example, this tests a few "hanging
actor" conditions more formally:

- that despite a hanging actor's task we can dump
  a `stackscope.extract()` tree on relay of `SIGUSR1`.
- the actor tree will terminate despite a shielded forever-sleep by our
  "T-800" zombie reaper machinery activating and hard killing the
  underlying subprocess.

Some test deats:
- simulates the expect actions of a real user by manually using
  `os.kill()` to send both signals to the actor-tree program.
- `pexpect`-matches against `log.devx()` emissions under normal
  `debug_mode == True` usage.
- ensure we get the actual "T-800 deployed" `log.error()` msg and
  that the actor tree eventually terminates!

Surrounding (re-org/impl/test-suite) changes:
- allow disabling usage via a `maybe_enable_greenback: bool` to
  `open_root_actor()` but enable by def.
- pretty up the actual `.devx()` content from `.devx._stackscope`
  including be extra pedantic about the conc-primitives for each signal
  event.
- try to avoid double handles of `SIGUSR1` even though it seems the
  original (what i thought was a) problem was actually just double
  logging in the handler..
  |_ avoid double applying the handler func via `signal.signal()`,
  |_ use a global to avoid double handle func calls and,
  |_ a `threading.RLock` around handling.
- move common fixtures and helper routines from `test_debugger` to
  `tests/devx/conftest.py` and import them for use in both test mods.
