Hardcoded limit to checkpoints retrieval for AgentCore LangGraph Saver

[ltoniazzi]

Seems that the get_events method defaults to 100 limit of events (here).

But it's always used without passing the limit param here.

So the default limit is always used and the user has no control over it.

Question:
Is this intentional? Because it seems that a thread_id memory with more than 100 nodes executions will be incomplete when retrieved from AgentCore.

Thanks @ltoniazzi, we are looking into this. Moving to an issue: #719
