Unlimited agent tool rounds

Agent stages no longer have an artificial cap on tool rounds per input or subagent turns. Previously, the default limits could cause agents to stop mid-task on complex operations. Both max_tool_rounds_per_input and subagent max_turns now default to unlimited, so agents run until they complete their work or hit the context window.
