* fix(agents): keep token budget signals for runs without a run_id #5410 moved every invocation without a non-empty string run_id onto str(id(runtime)). Two things break on that key: - SubagentExecutor passes the parent's run_id, None when the parent run has none (LangGraph Server, direct create_deerflow_agent callers), and reads the stop reason back with that None. The hard stop stored it under the id string, so a token-capped subagent reported a clean completion to the lead. - LangGraph gives each graph node its own Runtime wrapper, so the key changed between after_model and the next model call: the budget warning was never delivered, and each after_model counted every AIMessage in the thread. Key those invocations by Runtime.control, as LoopDetectionMiddleware does, release it in after_agent, and store the stop reason under the context run_id as given.

Move the anchor to the end on every lookup, as loop detection does, and note why execution_info.run_id is not consulted.
