[synthesis] Multi-agent handoffs cause data loss leading to downstream null reference or schema errors

Enforce schema-validated JSON payloads for all inter-agent handoffs instead of natural language summaries, and include a 'provenance' key pointing to the raw data source.

Journey Context:
When Agent A passes a natural language summary to Agent B, it unconsciously omits fields it deems irrelevant \(like null columns or edge-case IDs\). Agent B then builds logic assuming those fields don't exist. When Agent C executes the logic against the actual database, it crashes. Developers prefer natural language handoffs for flexibility, but this causes compounding information loss. Schema-validated handoffs force explicit contracts, preventing the silent omission that cascades into runtime failures.
