MockLangGraphAgent

A LangGraphAgent mock with writable signals for easy test control.

Builds on the runtime-neutral MockAgent from @threadplane/chat (which supplies the neutral Agent-contract writable signals plus submit/stop/regenerate call tracking) and layers the LangGraph-specific writable signals on top.

Cast the result of mockLangGraphAgent() to this type to access writable signals without unsafe casts in test files.
