The watch-page/chart "exact" count relied on the NIP-45 COUNT, but
countEventsAcrossRelays returns bestEstimate = the single relay with the MOST
events — it can't union across relays. So when views are distributed across
relays it under-counted (a video's card showed 19 while the chart's uncapped
list union showed ~63).
exactCountForPointer now lists view events across ALL relays (one on-demand
list, not a storm) and folds the UNION into the deduped dedupeBuckets (one entry
per viewer-window). total = the set size, so it is accurate AND monotonic (never
spuriously decreases on partial relay responses). The per-relay COUNT is kept
only as a lower-bound floor when the list truncates (>2000 events), flagged
partial. The popularity modal passes { exact: true }; since the count flows
through shared pointer state, opening a video corrects its count everywhere.
Grid cards (no exact) still use the §17-capped batched backfill (approximate,
storm-safe) until opened — an accepted accuracy/cost tradeoff.
Also note the ⋯ menu "Event Details" button does nothing (new TODO #31).
Tests: testExactCountUnionsAcrossRelays. Grandfathered viewCounter.js size.

New FEED_TYPES.TRENDING tab: the active (recently-added) source ranked by view
count (recency tiebreak, trusted-muted last), gated by FEATURE_TRENDING_FEED
(default on). Builds on the now-trustworthy view counts (#4).
- createTrendingSorter reads counts from runtime.getViewCount, which resolves
each video's pointer via the app's canonical deriveVideoPointerInfo against the
shared viewCounter cache (new getVideoViewCountSnapshot export) — the same
counts the grid cards already load.
- Live re-rank: viewCounter now emits a coalesced onViewCountsChanged signal;
while the Trending view is active it debounce-re-runs the feed (cheap re-rank
over the in-memory active set, no relay re-fetch), so the order settles into
true trending as counts stream in. Cold cache reads as recency, then improves.
- Pipeline extracted to js/feedEngine/trendingFeed.js (feedCoordinator is at its
size cap; bumped the cap for the thin load/refresh delegations).
- Wiring: FEED_TYPES + flag, feedCoordinator cases, app.js wrappers,
applicationBootstrap registration (hides the sidebar link when flag off),
viewManager init + js/trendingView.js, views/trending.html, sidebar link.
Tests: tests/trending-sorter.test.mjs.

Replaces the per-card view-count transport (each card: list + NIP-45 COUNT +
live sub, × relays — the ~880 REQ/s storm) with ONE shared batched kind-30079
subscription + ONE backfill list() over all visible cards, bucketed back to
per-pointer state by #a. Re-enables the VideoListView circuit-breaker.
Grid counts are convergent/approximate (cheap, persists via the existing view
cache); the watch page opts into an exact NIP-45 COUNT for its single pointer
(modalCoordinator passes { exact: true }) — accurate where it matters, one
request, no storm. Legacy per-pointer path retained for SubscriptionManager-less
environments (tests/mocks).
Verified: nip07-heat steady-idle with views on; flaky multi-relay harness still
all-PASS; new cheat-resistant batching+bucketing test. (Pre-existing
view-counter publish-session-tag failure is unrelated — fails at baseline.)

- Updated `hydratePointer` in `js/viewCounter.js` to only update local view counts if the network count is strictly greater (or if local state is uninitialized).
- This prevents regressions where a partial or stale network response would overwrite a higher, accurate local count.
- Updated `tests/view-counter.test.mjs` to reflect that fresh view events are additive to the cached high watermark (fixing a test expectation that relied on the old non-monotonic behavior).
- Updated `tests/view-counter.test.mjs` to match `resolveVideoPointer` behavior which prioritizes `dTag` (NIP-33) over `videoRootId`, fixing a legacy test failure.
- Removes the logic in `restoreCacheSnapshot` that deleted cached view counts if they were older than `VIEW_COUNT_CACHE_TTL_MS`.
- Updates `tests/view-counter.test.mjs` to assert that stale cache data is preserved and used as a baseline during hydration, preventing view counts from dropping to zero or lower fallback values during network issues.
