Managing context during tool runs

[pjsgsy]

Hi - I have a big issue trying to manage context during long runs where the gframework internally manages all tool iterations.

Hoping someone can point me in the right direction

1. Is there an intended hook point between tool iterations? e.g., an IToolCallInterceptor, a middleware delegate, or
   an event on ChatClientAgent?
2. Can ChatClientAgentOptions expose a per-iteration callback (before/after each tool-call round)?
3. Is IChatReducer intended to fire more than once per RunAsync? The current behavior (once only, before the first LLM
   call) makes it useless for long tool runs.
4. Is there a DelegatingChatClient hook point that fires between iterations inside the native loop?

I added post-stream compression, but it's not enough, and I cannot see a way to implement a hook that will help prevent a single 15-tool run from killing the conversation.

Thanks.
