Real-environment console logs revealed nip-07 login pegging the CPU and
starving encrypted-list decryption via relay REQ storms (~1000 REQ/s):
- moderationService.rebuildTrustedContacts emitted "contacts"
unconditionally, forming an emit->fetch->emit loop (~1600 kind-3 REQ/s).
Now emits only on actual change. Regression test added.
- Per-video live report (kind 1984) and view-count (kind 30079)
subscriptions fan out O(videos x relays) and re-fire on every flaky-relay
reconnect. Circuit-broken behind flags until batched (see refactor plan).
- onVideosShouldRefresh now coalesces forced reloads (2s leading-edge
throttle) so list-change signals can't drive a reload loop.
- nip-07 queue reserves one foreground slot; DM decryption demoted to LOW
so background DM backfill can't starve feed-driving lists. Test added.
