* fix(agents): keep the delegation ledger and summary in create_deerflow_agent graphs The SDK factory chain had no DurableContextMiddleware. SubagentLimitMiddleware counts a run's delegations from the ledger that middleware writes, so the per-run subagent total never tripped, and DeerFlowSummarizationMiddleware keeps compacted history in summary_text, which only that middleware puts back into model requests, so a summarized factory graph lost its history. Add it after ToolErrorHandlingMiddleware, ahead of summarization, where make_lead_agent has it. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * fix(agents): make RuntimeFeatures(token_budget=True) enforce the budget The factory built TokenBudgetMiddleware from TokenBudgetConfig(), whose enabled flag defaults to False, and every hook returns early on it. A graph created with token_budget=True had no warning, no hard stop and no token_capped.

The lead and subagent chains pair it with SystemMessageCoalescingMiddleware because strict backends reject that; the factory now does the same.
