giles 13e0254261 HS: MutationObserver mock + on mutation dispatch (+7 tests) ...

Parser: parse-on-feat now consumes `of FILTER` after `mutation` event-name,
where FILTER is `attributes`/`childList`/`characterData` ident or `@a [or @b]*`
attr-token chain. Emits :of-filter dict on parts. Compiler: scan-on threads
of-filter-info; mutation event-name emits `(do (hs-on …) (hs-on-mutation-attach!
TARGET MODE ATTRS))`. Runtime: hs-on-mutation-attach! constructs a real
MutationObserver with config matched to filter and dispatches "mutation" event
with records detail. Runner: HsMutationObserver mock with global registry;
prototype hooks on El.setAttribute/appendChild/removeChild/_setInnerHTML fire
matching observers synchronously, with __hsMutationActive guard preventing
recursion. Generator: dropped 7 mutation tests from skip-list, added
evaluate(setAttribute) and evaluate(appendChild) body patterns.

hs-upstream-on: 36/70 → 43/70. Smoke 0-195 unchanged at 170/195.
