This runs on every form submission with a CollectionType field and on every PropertyAccessor write to a collection-valued entity property. + +**Why not patch-shipped this pass:** `\in_array(..., true)` with `$strict=true` on objects checks identity (===), but on scalars checks `===`. The collection can contain mixed types (objects, scalars, arrays).

The optimizer's own `extractOrConditions` contains the pattern it exists to eliminate: per regex match it calls `Array.find` on an accumulator plus two `Array.includes` dedup checks.
