An Effect that resolves with a tuple of
PromiseSettledResult objects for each input effect
Remarks
Behaves like Promise.allSettled — all effects start concurrently and the
returned effect always succeeds with a tuple of PromiseSettledResult
objects. No effect is short-circuited on failure; every effect runs to
completion (or until the parent signal is aborted).
Runs all effects in parallel and collects every outcome, whether fulfilled or rejected.
