• #9982 4558fa6 Thanks @hntrl! - feat(langchain): add optional tools parameter to countTokensApproximately for more accurate token estimates when tools are bound to a model

• #9981 5f28338 Thanks @hntrl! - feat(agents): support returning Command from wrapModelCall middleware

  Allow wrapModelCall middleware hooks to return Command objects for advanced
  control flow (routing, state updates), matching the existing wrapToolCall
  pattern. The framework tracks the effective AIMessage through the middleware
  chain so outer middleware always receive an AIMessage from handler(), even
  when an inner middleware returns a Command.
