langgraph recently added a new context API: https://langchain-ai.github.io/langgraph/agents/context/#static-runtime-context\

I added this to one of our similar templates, memory-agent. Here's that PR: https://github.com/langchain-ai/memory-agent/pull/15\
I had a follow up adding a post_init instead of init as well: https://github.com/langchain-ai/memory-agent/pull/16\

Please do the same for this repo. Make sure to update docs as well.

Please use the runtime: Runtime[Context] pattern when possible. Only use get_runtime if you're in a tool.
