HS runtime + generator: make, Values, toggle styles, scoped storage, array ops, fetch coercion, scripts in PW bodies

Browse Source 
Runtime (lib/hyperscript/ + shared/static/wasm/sx/hs-*.sx):
- make: parser accepts `<tag.class#id/>` selectors and `from <expr>,…`; compiler
  emits via scoped-set so `called <name>` persists; `called $X` lands on
  window; runtime dispatches element vs host-new constructor by type.
- Values: `x as Values` walks form inputs/selects/textareas, producing
  {name: value | [value,…]}; duplicates promote to array; multi-select and
  checkbox/radio handled.
- toggle *display/*visibility/*opacity: paired with sensible inline defaults
  in the mock DOM so toggle flips block/visible/1 ↔ none/hidden/0.
- add/remove/put at array: emit-set paths route list mutations back through
  the scoped binding; add hs-put-at! / hs-splice-at! / hs-dict-without.
- remove OBJ.KEY / KEY of OBJ: rebuild dict via hs-dict-without and reassign,
  since SX dicts are copy-on-read across the bridge.
- dom-set-data: use (host-new "Object") rather than (dict) so element-local
  storage actually persists between reads.
- fetch: hs-fetch normalizes JSON/Object/Text/Response format aliases;
  compiler sets `the-result` when wrapping a fetch in the `let ((it …))`
  chain, and __get-cmd shares one evaluation via __hs-g.

Mock DOM (tests/hs-run-filtered.js):
- parseHTMLFragments accepts void elements (<input>, <br>, …);
- setAttribute tracks name/type/checked/selected/multiple;
- select.options populated on appendChild;
- insertAdjacentHTML parses fragments and inserts real El children into the
  parent so HS-activated handlers attach.

Generator (tests/playwright/generate-sx-tests.py):
- process_hs_val strips `//` / `--` line comments before newline→then
  collapse, and strips spurious `then` before else/end/catch/finally.
- parse_dev_body interleaves window-setup ops and DOM resets between
  actions/assertions; pre-html setups still emit up front.
- generate_test_pw compiles any `<script type=text/hyperscript>` (flattened
  across JS string-concat) under guard, exposing def blocks.
- Ordered ops for `run()`-style tests check window.obj.prop via new
  _js_window_expr_to_sx; add DOM-constructing evaluate + _hyperscript
  pattern for `as Values` tests (result.key[i].toBe(…)).
- js_val_to_sx handles backticks and escapes embedded quotes.

Net delta across suites:
- if 16→18, make 0→8, toggle 12→21, add 9→10, remove 11→16, put 29→31,
  fetch 11→15, repeat 14→26, expressions/asExpression 20→25, set 27→28,
  core/scoping 12→14, when 39→39 (no regression).
