LangGraph Workflow Checkpointing and Interrupts - Part 1/3

Learn how to implement workflow checkpointing and human-in-the-loop interruptions in LangGraph. This tutorial covers stateful execution with the InMemorySaver checkpointer, interrupt handling, and thread management for resumable workflows.

Zen Koan Explanation:
The code uses `InMemorySaver` to checkpoint the essay's state (folding it into a "paper crane") and ties it to a `thread_id` (pinning it to the crane's wing). When `interrupt()` pauses execution, the workflow waits for external input (the "breath of life") to resume, ensuring the essay isn't recomputed—just as the crane remains intact until revived.
