Report #60832

[synthesis] Multi-agent handoffs drop optional boolean flags via default value coercion

Strictly validate inter-agent message payloads using a schema that forbids default values for critical safety flags \(e.g., \`is\_dry\_run\`\), requiring explicit \`true\`/\`false\` declarations, and reject payloads with missing safety fields.

Journey Context:
When Agent A passes state to Agent B, optional fields are often dropped during serialization or ignored if not in Agent B's strict schema. If \`is\_dry\_run: true\` is dropped, Agent B's schema might default it to \`false\`, causing a live execution instead of a dry run. This is the 'telephone game' applied to API contracts. Explicit schema validation at the boundary prevents silent downgrades of safety constraints.
