Claude 6ac2903a3a fix(quartz): live negentropy index — same-batch displacement, no-op kind-5, rebuild cap

Audit follow-ups on the live NIP-77 index, all with the store/scan
equivalence test extended to cover them:

- Same-batch replaceable displacement left a dead id in the index.
  applyAfterCommit applied all removes before all adds, so when a later
  row in one transaction displaced an earlier row of the same batch (two
  versions of one replaceable — the mirror-backfill hot path), the
  displaced row's remove no-op'd against an index that hadn't taken its
  add yet, then the add re-inserted it: the index advertised an id the
  trigger had already deleted. recordAccepted now cancels the pending add
  instead of queueing a remove (added is a LinkedHashSet for O(1)
  cancel).

- A kind-5 that deleted nothing (a delete broadcast for events this relay
  never stored — the common case) still invalidated the whole index,
  forcing a full-scan rebuild under the writer mutex on the next
  NEG-OPEN. DeletionRequestModule.insert now returns the rows it deleted;
  recordAccepted only invalidates when that count is > 0, else records the
  kind-5 as a plain row.

- The first NEG-OPEN over a corpus larger than the serve cap scanned the
  whole table uncapped, built a full index that could never produce a
  snapshot, and then maintained it forever for zero benefit.
  liveNegentropySnapshot now caps the rebuild scan at maxEntries + 1 and
  leaves the index unpopulated when the corpus is over-cap (the scan path
  answers NEG-ERR, as before).

- delete/deleteExpired/clearDB invalidate() moved inside the writer mutex
  so no NEG-OPEN can seal a snapshot of just-deleted rows, and no
  concurrent rebuild can be discarded by a late invalidate.

Also corrects the ~40 B/event heap figure to ~140 B (IdAndTime keeps the
id as a 64-char hex string, not 32 bytes) in the strategy/plan docs.
