Native islands ran their use_future polling loops on a fixed
cadence regardless of whether the user was looking at them.
With multiple islands open in a saved space this drove ~14k
needless requests/hour against backends.

Each polling site now uses hero_archipelagos_core::use_focus_poll,
which gates the body on is_window_focused(window_id). When the
window's class flips off window-shadow-focused, the body is
skipped; the interval keeps ticking so polling resumes within
one cycle of refocus.

connection-status.js (iframe-mode fallback) gains a parallel
parent-DOM check so iframe pages also pause when their containing
window isn't focused.

Depends on hero_archipelagos PR 194.
