Module fork 

Fork engine — lightweight concurrent multi-perspective execution.

Each “lens” shares the parent session’s provider, tools, and messages but gets its own system prompt + task. All lenses run concurrently via a tokio [Semaphore]-bounded Synapse.

Fork is NOT a subprocess. It is an in-process concurrent provider call.
