6a1dca113e chore: move ToolNode improvements back to langgraph (#33634) 
Moving all `ToolNode` related improvements back to LangGraph and
importing them in LC!
pairing w/ https://github.com/langchain-ai/langgraph/pull/6321

this fixes a couple of things:
1. `InjectedState`, store etc will continue to work as expected no
matter where the import is from
2. `ToolRuntime` is now usable w/in langgraph, woohoo!

c456c8ae51 fix(langchain): fix response action for HITL (#33131) 
Multiple improvements to HITL flow:

* On a `response` type resume, we should still append the tool call to
the last AIMessage (otherwise we have a ToolResult without a
corresponding ToolCall)
* When all interrupts have `response` types (so there's no pending tool
calls), we should jump back to the first node (instead of end) as we
enforced in the previous `post_model_hook_router`
* Added comments to `model_to_tools` router so clarify all of the
potential exit conditions

Additionally:
* Lockfile update to use latest LG alpha release
* Added test for `jump_to` behaving ephemerally, this was fixed in LG
but surfaced as a bug w/ `jump_to`.
* Bump version to v1.0.0a10 to prep for alpha release
