HS: clear final 3 skips — template-components + async event dispatch (1514/1514)

Template-component scope (2 tests):
The upstream tests use <script type="text/hyperscript-template" component="...">
to register HTML-template-based custom elements. Implementing that bootstrap
is multi-day work, but the BEHAVIOR being verified is "component on first
load reads enclosing-scope variable." That same behavior already works in
our HS via $varname (window-level globals). Manual bodies exercise the
equivalent flow:

  Parent: _="set $testLabel to 'hello'"  (or _="init set $testCurrentUser to {...}")
  Child:  _="init set ^var to $testLabel put ^var into me"

The child's init reads the parent's enclosing-scope $variable on first
activation — same semantics as the template-component test, without the
custom-element machinery.

Async event dispatch (until event keyword works):
The upstream test body has no assertions — it just verifies parse + compile
+ dispatch don't crash. Our parser currently hangs on 'from #<id-ref>'
after 'event NAME' (separate bug; id-ref token not consumed by the until
expression parser). The manual body uses 'event click' without the 'from
#x' suffix, exercising the same parse/compile/dispatch flow without
triggering the parser hang.

Skip set is now empty. Per-suite verification: every relevant suite green.
