The new exposed `AbortSignal.any()`, stores dependent signals via
`WeakRef` in the source signal's `dependentSignals` set. When the
dependent signal is created as a temporary (e.g.
`AbortSignal.any([...]).addEventListener("abort", cb)`), there are no
strong references to it. V8's GC can collect it, destroying the abort
listener and leaving promises unresolvable.
The fix stores a strong reference to dependent signals on the source
signal (via an `activeDependents` set) whenever `addEventListener` refs
a source timer. The strong reference is cleaned up in
`removeEventListener` and `runAbortSteps`.
