Sarah Wooders b888c4c17a feat: allow for conversation-level isolation of blocks (#8684) 
* feat: add conversation_id parameter to context endpoint [LET-6989]

Add optional conversation_id query parameter to retrieve_agent_context_window.
When provided, the endpoint uses messages from the specific conversation
instead of the agent's default message_ids.

* chore: regenerate SDK after context endpoint update [LET-6989]

* feat: add isolated blocks support for conversations

Allows conversations to have their own copies of specific memory blocks (e.g., todo_list) that override agent defaults, enabling conversation-specific state isolation.
