Mostly due to magic from @oremanj (a super-end-level-boss) where we slap
in a little bit of `.from_asyncio`-type stuff to run a `trio`-task from
`asyncio` code
I'm not gonna go into tooo too much detail but basically the primary
thing needed was a way to (blocking-ly) invoke a `trio.lowlevel.Task`
from an `asyncio.Task` (which we now have with a new
`run_trio_task_in_future()` thanks to the "aforementioned jefe") which
we now invoke from a dedicated aio case-branch inside
`.devx._debug.pause_from_sync()`. Further include a case inside
`DebugStatus.release()` to handle using the same func to set the
`repl_release: trio.Event` from the `asyncio` side when releasing the
REPL.
Prolly more refinements to come ;{o
