• #11087 534b43a Thanks @christian-bromann! - fix(langchain): keep tool call streams pending across any tool interrupt

  A raw interrupt() raised from inside a tool surfaced as a tool-error and
  rejected the call's un-awaited output promise, producing an unhandled
  rejection that crashed HITL runs. The tool-call stream transformer now treats
  any serialized graph interrupt as control flow (the call stays pending and
  resumes), not just humanInTheLoopMiddleware interrupts.
