Neil e7563c63f1 fix: fence browser recovery to attach inventory placements (#18910)
* fix: fence browser recovery to attach inventory placements

* refactor: name the attach-inventory fence and make its test deterministic

Extract the placement check into isPlacedAsObservedAtAttach so the recovery
filter stays a flat list of named predicates, and document that omitting
pagePlacementsAtAttach recovers against unfenced live state.

Replace the 30-microtask drain in the post-attach regression with the handler's
own completion: attach only settles after recovery returns, so awaiting the
dispatch orders the assertions instead of guessing at a microtask count.

Verified by forcing the fence open: both regressions fail (the post-attach one
in 60ms on a retired placement) and the other 27 still pass.

* test: settle the attach handler even when the regression fails early

The barrier ran inline, so a waitFor timeout or the placement guard left the
attach handler parked on a promise nothing awaited. Hoist it into settleAttach
and call it from a finally as well; cleanup is guarded and the dispatch promise
is already settled, so the second call is a no-op.
