Fix HS put-into and query: compiler emits hs-query-first, runtime uses real DOM

Two bugs found by automated test suite:
1. compiler.sx: query → hs-query-first (was dom-query, a deleted stub)
2. compiler.sx: emit-set with query target → dom-set-inner-html (was set!)
3. runtime.sx: hs-query-first uses real document.querySelector
4. runtime.sx: delete hs-dom-query stub (returned empty list)

All 8/8 HS elements pass: toggle, bounce+wait, count, add-class,
toggle-between, set-innerHTML-eval, put-into-target, repeat-3-times.
