Claude 73ee5cce99 perf(quartz/geode): serve full-set NEG-OPENs from the live negentropy index
Milestones 2-3 of quartz/plans/2026-07-03-incremental-negentropy-storage.md.

SQLiteEventStore now maintains the LiveNegentropyIndex when the strategy
opts in (geode's does by default; [negentropy].live_index = false turns
it off; app-side stores are untouched):

 - Write paths collect a LiveIndexDelta and apply it after COMMIT while
   still holding the writer mutex — rolled-back savepoint rows never
   reach the index and updates land in exact commit order (also vs the
   rebuild, which runs under the same mutex).
 - Replaceable/addressable overwrites report the row their BEFORE-INSERT
   trigger displaces via one indexed pre-SELECT that mirrors the trigger
   predicate (including the NIP-01 lowest-id tie-break and the
   d_tag-NULL case).
 - Paths that can't itemize (kind-5, vanish, delete-by-filter/id,
   expiration sweeps, clearDB) invalidate; the next NEG-OPEN rebuilds
   from one scan on the writer connection.
 - Until that first NEG-OPEN populates the index, ingest pays zero
   bookkeeping — the populated check happens under the writer mutex so
   it can't race the rebuild.

LiveEventStore serves a single unconstrained filter (the relay-relay
sync default; relayBench sends exactly this) from the index; everything
else keeps the scan+seal path and its single-slot cache.

Micro-benchmark at 50k events (LiveNegentropyBenchmark, in-container):
scan+seal cold path 80-100 ms; index post-write open 9-16 ms (~5-10x).
The relayBench A/B is the acceptance gate and comes next.

Correctness: LiveNegentropyIndexStoreTest asserts index content ==
snapshotIdsForNegentropy scan after every mutation pattern (overwrites,
losers, kind-5 rebuilds, filter deletes, mixed-outcome batches,
transactions); the full geode suite (NIP-77 + interop sync tests) runs
with the index on.
