Claude 91a7261555 test(sync): toggle live negentropy index to isolate its O(n)-insert backfill cost
Adds -DsyncLiveIndex and a fast (no-live-index) source preload. Rate curves show
geode's mirror sustains ~20k ev/s with the live index off, but collapses to
O(n^2) with it on: the LiveNegentropyIndex is a sorted ArrayList whose per-event
insert is O(n), and a backfill delivers historical (non-near-tail) events, so
every insert memmoves ~n/2 entries.
