Closes #10

Summary

  • Remove force-pins on langgraph==1.0.4 / langgraph-checkpoint==3.0.1 / langgraph-prebuilt==1.0.5 / langgraph-sdk==0.2.14
  • Upgrade langchain stack so current langgraph-checkpoint (4.x) works with Reviver(allowed_objects=...)
  • Keep direct langgraph>=1.2.5,<1.3.0 (matches langchain 1.3.x); checkpoint/prebuilt/sdk resolve transitively
  • Adapt BaseMessage.text() → .text property for langchain-core 1.5.x

Resolved versions (uv.lock)

Package Before After
langchain-core 1.1.1 1.5.1
langchain 1.1.2 1.3.14
langgraph 1.0.4 1.2.9
langgraph-checkpoint 3.0.1 4.1.1
langgraph-prebuilt 1.0.5 1.1.0
langgraph-sdk 0.2.14 0.4.2

Test plan

  • uv sync --frozen
  • uv run python manage.py test — 248 OK (6 skipped)
  • Import consumers_graph CompiledStateGraph OK
  • Confirm Reviver.__init__ accepts allowed_objects
  • Manual smoke: WebSocket chat + graph path (consumers_graph)

Closes #10

Remove force-pins on langgraph-checkpoint/prebuilt/sdk and bump
langchain-core (and companions) so checkpoint 4.x Reviver(allowed_objects=...)
works. Keep langgraph on a supported range matching langchain 1.3.x.
Also switch BaseMessage .text() calls to the .text property.
