T4: workstreams.md and dependencies.md now call /state/deps instead of the
full /state/summary — removes 2 heavy 10-table queries per 60 s cycle.
T5: index.md's 4 independent polling loops (summaryState, sbomSnapState,
regsState, wsChartState) consolidated into a single pageState generator
with one Promise.all batch and a shared backoff counter.
T6: config.js gains waitForVisible(ms) — pauses polling entirely while the
tab is hidden and fires immediately on visibilitychange. pollDelay()
simplified (hidden-tab POLL_HIDDEN logic removed). All 16 polling pages
migrated from await sleep(pollDelay(...)) to await waitForVisible(pollDelay(...)).
CUST-WP-0039 complete — all 6 tasks done.
