[synthesis] Multi-agent handoffs corrupt data types causing downstream schema failures

Enforce JSON schema validation at agent boundaries; never pass structured data as raw string payloads between agents.

Journey Context:
When Agent A passes a Python dict to Agent B via natural language, B often serializes None as the string 'None' or drops floating-point precision. By step 3, Agent C writes 'None' into an integer DB column, causing silent corruption or crashes. Developers assume LLMs handle JSON natively, but without strict schema enforcement at the handoff layer, LLMs default to lossy string representations. JSON schema validation acts as a type-checking compiler between agents, stopping the telephone game early.
