Second slice of docs/zap-tally-plan.md §4. runBatch now queries kinds
[9735, ZAP_TALLY_KIND] in one call and folds both sources:
- 9735 receipts: unchanged sum, but now also records each receipt's
payment_hash (from its bolt11) for cross-source dedup.
- bitvid tallies: verifyBitvidZapTally (preimage + description-hash bound),
amount from the bolt11, pointers from the embedded zap request; counted
once per payment_hash so a payment that yields BOTH a 9735 and a tally is
never double-counted.
Entries gain a paymentHashes set. Counting is gated by isTallyEnabled
(singleton reads FEATURE_ZAP_TALLY live). The existing "relay wins" prune
clears the optimistic/ledger overlay once a real tally or receipt lands, so
the sender's own published tally reconciles the instant bump with no extra
plumbing.
Tests: cross-source/same-payment dedup, invalid-tally rejection, flag gating
(tests/zap-totals.test.mjs). Lint + build green.
