[architecture] System prompts and persona instructions bleeding across agents when context is handed off

Strictly isolate system prompts by wrapping agent handoffs in a structured envelope that explicitly separates the new agent's system prompt from the inherited conversational context.

Journey Context:
When Agent A hands off to Agent B, it is tempting to just append B's instructions to A's history. This causes B to inherit A's persona and constraints, leading to confused behavior. Agents must treat system prompts as immutable, isolated execution environments, only sharing the factual data payload of the task.
