Convention sweep (user req): all `tractor.open_nursery()`
bindings in test + example code use `an: ActorNursery` (`n`,
`nursery` + several tractor-nurseries confusingly named `tn`
are renamed); `trio.open_nursery()` bindings stay `tn` (incl.
`concurrent_actors_primes.py`'s inner trio nursery, renamed
`n` -> `tn` to match).
Purely mechanical, function-scoped renames — prose "nursery"/
"an" in docstrings/comments untouched; func-arg kwargs like
`portal.run(func, n=value)` untouched.
Gate: renamed test modules green on `trio`; full debugger suite
(28p/6s) + example-runner (21p) green.

4 example scripts of the #477 removal sweep, each exercised by
`test_docs_examples.py`,
- `actor_spawning_and_causality.py`: the simplest possible
`to_actor.run()` demo — private call-scoped nursery, block on
and print the one-shot's result.
- `remote_error_propagation.py`: blocking `to_actor.run(an=n)`
raises the boxed `AssertionError` in the caller's task,
cancelling the sibling daemons.
- `parallelism/single_func.py`: bg-burn a core in the parent via
a local task-nursery while the one-shot burns (and returns
from) a subactor.
- `a_trynamic_first_scene.py`: donny + gretchen wait on each
*other* so their one-shots run concurrently in a local
task-nursery against a shared `an` (mirrors the migrated
`test_trynamic_trio`).
Gate: all 4 green via the example-runner suite.

Demo both flavors of the new API in a runnable script
(auto-collected by `test_docs_examples.py`),
- the fully-implicit one-shot which boots (and tears down) the
actor-runtime around a single `to_actor.run()` call,
- the concurrent "worker-pool-ish" prime-check pattern: a local
`trio` task nursery scheduling one-shots against a shared
caller-managed `an`, mirroring (in miniature) the neighboring
`concurrent_actors_primes.py` example per issue #477.

`run_in_actor()` is slated to become a hilevel wrapper
(`runtime/_supervise.py` "TODO: DEPRECATE THIS"), so the showcase
`we_are_processes.py` shouldn't lead with it. Move it to the modern
API: each `worker_<i>` subactor runs a `@tractor.context`
`endpoint()` that `started()`-hands its name + pid back over
`Portal.open_context()` and parks; the root sleeps then raises on
purpose so the runtime reaps the whole tree (zero zombies).
The subs spawn concurrently from bg `trio.Task`s so each child's
cold `import tractor` (~0.4s, see #470) overlaps instead of
stacking; a comment flags the coming `main_thread_forkserver`
backend (#463) which'll make serial spawns cheap enough to just
loop.
Match the landing prose to the snippet — name the `Context` +
`started()` handshake it now leads with.
Also, document `--watch examples` on the `sphinx-autobuild` cmds so
edits to `literalinclude`-d example scripts (which live outside
`docs/`) live-reload too.

Rename `parallelism/_concurrent_futures_primes.py` ->
`concurrent_futures_primes.py` so the example-runner
(`test_docs_examples.py`) stops skipping it (leading `_` =
excluded) and CI finally exercises the `concurrent.futures`
baseline we compare against in the new parallelism guide.
Deats,
- keep the original executor code verbatim in a sync
`check_primes()` fn for clean docs excerpting,
- add module docstring + zero-arg `async def main()` +
`trio.run(main)` guard per the runner conventions.

Swap the deprecated `portal.result()` calls for the modern
`.wait_for_result()` spelling in,
- `a_trynamic_first_scene.py` (x2)
- `actor_spawning_and_causality.py`
- `parallelism/single_func.py`
These 3 are literalinclude'd by the new docs tree so the rendered
code must teach the current api; the `debugging/` set still calls
`.result()` (pexpect pattern-matched tests, left for a follow-up
sweep).

- `trio_typing` is nearly obsolete since `trio >= 0.23`
- `exceptiongroup` is built-in to python 3.11
- `async_generator` primitives have lived in `contextlib` for quite
a while!
