View counts inflated. viewCounter.js dedupes locally by (viewer, time-window)
correctly, but the published events couldn't be deduped by relays:
generateViewEventDedupeTag built the kind-30079 `d` tag with random entropy +
exact timestamp, so every view was a UNIQUE event. And exactCountForPointer runs
a NIP-45 COUNT (raw event count, no dedupe) and bumped the displayed total up to
it (max(deduped, raw)). Net: reloads / multi-device / re-watches each added a
view.
Make the `d` tag deterministic and window-bucketed (scope:viewer:bucket, no
entropy) so kind-30079 view events are genuinely parameterized-replaceable:
relays keep one event per (viewer, video, window), so the cheap NIP-45 COUNT
becomes accurate AND scalable and the raw count stops inflating. buildViewEvent
no longer invents a random `d` tag (the only production caller, publishViewEvent,
always supplies the deterministic one). Pre-existing entropy events age out over
the backfill horizon.
