Note

Derive originators from cursor arrays in SelectGatewayEnvelopesByOriginators

• Removes OriginatorNodeIds from SelectGatewayEnvelopesByOriginatorsParams; originators are now inferred from the CursorNodeIds array
• Rewrites the SQL query in envelopes_v2.sql to use LATERAL joins per originator, applying per-originator filtering, sequencing, and row limits
• Updates SetVectorClockByOriginators to accept an explicit originator list and populate cursor arrays with sequence positions from the vector clock, defaulting to 0 for missing entries
• Adds routing in fetchEnvelopes to use SelectGatewayEnvelopesBySingleOriginator for single-originator queries
• Risk: Breaking change for all callers — they must now include desired originators in cursor arrays rather than a separate parameter

this is some very good stuff!

can you also update the benchmarks/results listing?
