The following command in my proyect, after update the langgraph & langchain packages up to 1.0.0:

uv lock --upgrade
gives me the following result:

× No solution found when resolving dependencies:
 ╰─▶ Because all versions of langgraph-codeact depend on langgraph>=0.3.5,<0.4.0 and your project depends on langgraph>=1.0.4, we can
     conclude that your project and all versions of langgraph-codeact are incompatible.
     And because your project depends on langgraph-codeact, we can conclude that your project's requirements are unsatisfiable.
