[synthesis] Multi-agent handoff drops leading zeros and corrupts IDs via CSV serialization

Mandate JSON or Parquet for inter-agent state handoffs, and explicitly define schema types in the handoff metadata. Never use CSV for agent-to-agent data transfer.

Journey Context:
Agent A extracts data and serializes to CSV to pass to Agent B. Agent B uses a standard library \(like Pandas\) to read it, which infers types automatically, dropping leading zeros from ZIP codes or turning mixed-type columns into floats. Agent B passes this corrupted data to Agent C, which writes it to the DB. The original data is permanently corrupted. Developers allow CSV because it is human readable, but for agents, it is a type-unsafe nightmare. JSON with explicit types preserves data fidelity across boundaries.
