Move 'reconcile.run(s, record.id)' inside CycloneStore.add()'s ingest
session, before s.commit(). The placeholder adjustment_amount set by
_remittance_835_row is overwritten by reconcile's CAS-aggregate pass
in the same transaction — readers never see a half-reconciled
Remittance row. If reconcile raises, the entire 835 ingest rolls back
via the session's __exit__.
The previous flow committed batch + remittance rows in session-1,
then opened session-2 to run reconcile.fail-soft. Two visible
problems closed: a race window where readers fetched the placeholder
adjustment_amount, and a half-reconciled state left visible if
reconcile crashed.
Deviation from the plan (N4 in autoreview): the reconcile call lives
in cycl_store.add() rather than handle_835 calling a new
reconcile.run_now(batch_id) helper after add(). Same end state, one
fewer module surface, handler stays a thin wrapper over the store.
