giles b9a24d5870 web: re-boost swapped content from the [sx-boost] ancestor (fixes back-then-click full reload) ...

After a fragment swap, process-elements(target) -> process-boosted(target) only
boosted [sx-boost] containers that are DESCENDANTS of the swap target. But the
swap target (#content) is nested UNDER the boost wrapper (<div sx-boost="#content">
<div id="content">), so re-boosting scoped to the target found nothing — the
swapped-in links never got bound. Only the initial document-wide boot boost
worked, so: home->sub worked (home links boosted at boot), but Back restored the
home content unboosted, and the next click did a full page reload. (Post-page
links were unboosted too; Back just exposed it.)

process-boosted now ALSO boosts from the nearest [sx-boost] ANCESTOR of root
(dom-closest), so any swap target inside a boost scope gets its links rebound.
is-processed? guards keep it idempotent.

spa-check: the back-button test now clicks AGAIN after Back and asserts it's a
SPA nav (no full reload) — would have caught this. .sxbc regenerated.

Verified: spa-check 4/4 (incl. click-after-back).
