The known-flaky dynamic pubsub test's 3 fire-and-forget spawn
sites (#477 removal),
- the forever-streaming `publisher` + N `consumer` one-shots now
bg-schedule as `to_actor.run(fn, an=n)` tasks in a local `trio`
task-nursery (`publisher`'s rendezvous name still derives from
`fn.__name__`).
- the simulated user-cancel raise (`KeyboardInterrupt` /
`TooSlowError` params) cancels the task-nursery, each one-shot
reaping its subactor via `to_actor.run()`'s shielded
`Portal.cancel_actor()`; `_run_and_match()`'s existing
`BaseExceptionGroup.split()` walk covers the (possibly nested)
relay shapes unchanged.
- spawns now issue concurrently rather than sequentially —
comment on the fork-backend budget updated to match.
Gate: both params x4 runs green on `trio` + x1 on `mp_spawn`;
full module green.
