giles 1613f551ef HS add/append: Set dedup, @attr support, when-clause result tracking

- runtime hs-add-to!/hs-append: dedupe on list targets (Set semantics)
- compiler emit-set: set result to X now syncs it too
- compiler append!: handle (local)/(ref) targets via emit-set so scoped
  vars get rebound to the returned list
- parser add/remove: accept bare @attr (not just [@attr])
- parser add-attr: support when-clause → emits add-attr-when
- compiler add-class-when/add-attr-when: collect matched items into
  the-result / it so subsequent "if the result is empty" works

+6 upstream tests in early range (add 13→17, append 10→12).
