Sweep the `examples/debugging/` set for basic typing: add `-> None`
to all 16 bare `async def main()`s and annotate the clean
single-line `open_nursery()` bindings as `tractor.ActorNursery`.
Kept to the unambiguous, runtime-safe cases (these breakpoint/crash
demos can't be run headless); the heterogeneous
multi-line/paren-group nursery bindings + `current_actor()` returns
are left for a later pass. Continues the examples-typing bullet in
#472.

Since turns out we didn't have a single example using that API Bo
The test granular-ly checks all use cases:
- `.post_mortem()` manual calls in both subactor and root.
- ensuring built-in RPC crash handling activates after each manual one
from ^.
- drafted some call-stack frame checking that i commented out for now
since we need to first do ANSI escape code removal due to the
colorization that `pdbp` does by default.
|_ added a TODO with SO link on `assert_before()`.
Also todo-staged a shielded-pause test to match with the already
existing-but-needs-refinement example B)
