[frontier] Type-unsafe agent handoffs causing runtime context corruption in Swarm

Enforce Pydantic BaseModel schemas for all context\_variables passed during handoffs, validating at entry/exit points with strict mode

Journey Context:
Swarm passes context\_variables as untyped dicts. When Agent A hands off to Agent B, key mismatches cause silent failures or agents acting on stale keys. By wrapping context in Pydantic models, you get static analysis and runtime validation. This prevents 'context drift' where agents expect different keys. The tradeoff is slight boilerplate, but it eliminates an entire class of integration bugs in multi-agent flows that only appear in production.
