HS: hyperscript:before:init / :after:init events (+2 tests)

Browse Source 
integration.sx hs-activate! now wraps the activation block in a cancelable
hyperscript:before:init event (dispatched on the el via dom-dispatch which
returns the dispatchEvent boolean — true unless preventDefault was called).
On success it dispatches hyperscript:after:init at the end. Both events
bubble so listeners on a containing wa work-area receive them. Generator
gets two hand-rolled deftests that exercise the new dispatch via
hs-boot-subtree!: one captures both events into a list, the other
preventDefaults before:init and asserts data-hyperscript-powered is absent.

hs-upstream-core/bootstrap: 20/26 → 22/26. Smoke 0-195: 170 → 172.

Remaining 4 cluster-29 tests need stricter parser error-rejection
(hs-upstream-core/parser, parse-error event); larger than a single
cluster budget — leave as untranslated for now.
