fix(xl-ai): Array.from on filtered iterator — tool calls never marked complete

s.values() returns a MapIterator/SetIterator, not an array. Calling
.filter() directly on an iterator throws TypeError or silently fails
depending on the runtime.

Move .filter() after Array.from() to fix tool call completion detection.

Fixes #2933
