Previously, when ensure_config was called with multiple configs (e.g.
Pregel.stream's ensure_config(self.config, config)), a later config's
configurable dict fully overwrote an earlier one. This caused values
bound via with_config({"configurable": {...}}) to be silently dropped
whenever the invoke-time config supplied any other configurable key.
Concretely, create_agent binds {configurable: {ls_agent_type: 'root'}}
via with_config, and any real invocation with a checkpointer supplies
{configurable: {thread_id: ...}} at invoke time. The bound ls_agent_type
was dropped, so no root-level runs were tagged with ls_agent_type='root'
in LangSmith.
Fix: merge the configurable dict across configs (stdlib merge_configs in
langchain_core already does this correctly; langgraph's merge_configs
helper in this same file also does this at line 109). Invoke-time values
still override bound values when keys collide.
Adds a regression test in tests/test_utils.py.
Allows us to put some more information for tracing purposes (e.g.,
ls_integration) without dumping it into the streaming APIs (good for
performance)
Move some other metadata into tracing only since it's not needed in
streaming APIs

- This more closely remembers the environment they're used in, so it's what we should be testing
- Remove unnecessary pytest-asyncio dependency, use anyio pytest plugin instead
- Convert remaining async tests using only memory checkpointer to use all existing ones
