v0.1.0

The first minor release. Through v0.0.66 the project bumped only the patch component; a backlog of breaking changes made that counter misleading, so releases now move the minor.

Breaking changes

• chat: provideChat(), ChatConfig and CHAT_CONFIG are removed. No component ever read the token, so calling it configured nothing — <chat> is configured through its inputs. Delete the call and the import.
• chat: @langchain/core is no longer a peer dependency; nothing in the published package imports it. It remains a peer of @threadplane/langgraph, so keep installing it alongside the adapter.
• middleware: the JavaScript router's default toolsNode is now server_tools. tools cannot be a node name on a graph that uses clientToolsChannel(), because LangGraph shares one namespace between node names and state channels.
• langgraph: streamErrorAt().classification is now .kind, carrying the AgentError kind rather than the error's constructor name.
• langgraph: LangGraphAgent.interrupt is required rather than optional; the adapter always provides it.

Also in this release

provideAgent() now provides AGENT_LIFECYCLE; the lifecycle registry is root-provided so agents register regardless of injector depth; MockAgentTransport.emit()/emitError()/close() are awaitable and gain flush(); both adapters warn in development when several provideAgent(ref, …) calls share an injector; provideFakeAgent() accepts a script; render resolves repeated-element readiness, props, action params and the render host in each row's own scope, validates JSON-pointer paths, and implements confirm/preventDefault/onSuccess/onError.

⚠️ Breaking Changes

• chat: remove provideChat(), fix app-level markdown registry overrides, and three API cleanups (#1055)
• middleware: server_tools router default; Python emit_custom_event helper (#1052)
  the default is now 'server_tools'. Rename your server tool
  node to server_tools and drop the override, or keep the override pointing at
  whatever name your node uses. There is no shim. The Python package's
  route_after_agent() keeps tools_node="tools"; Python LangGraph has no such
  namespace collision.
  Two integration specs record the behavior: one invokes a graph whose ToolNode
  is named server_tools with no override and asserts the tool actually ran (it
  failed with "Branch condition returned unknown or null destination" before the
  fix), and one pins the addNode('tools', …) throw so the reason is written down.
