@memfork/langgraph v0.1.0

@memfork/langgraph v0.1.0

Drop-in LangGraph checkpointer that stores every graph state snapshot on Sui (via MemWal). Each LangGraph thread maps to a MemForks branch — enabling cross-agent memory merges.

Install
```bash
npm install @memfork/langgraph @memfork/core
```

Usage
```typescript
import { createMemForksCheckpointer } from "@memfork/langgraph";

const checkpointer = await createMemForksCheckpointer({
treeId: process.env.MEMFORK_TREE_ID!,
signer: process.env.MEMFORK_PRIVATE_KEY!,
memwal: {
accountId: process.env.MEMFORK_MEMWAL_ACCOUNT!,
delegateKey: process.env.MEMFORK_MEMWAL_KEY!,
},
});

const app = new StateGraph(MessagesAnnotation)
.addNode("agent", myNode)
.compile({ checkpointer });
```

What it does

• Implements BaseCheckpointSaver — drop-in replacement for MemorySaver
• Each put() commits serialised graph state to MemWal and anchors the blob on-chain
• getTuple() / list() restores state via semantic recall
• Thread IDs map to branches: thread/<thread_id>
• proposeMerge() for cross-agent state reconciliation via on-chain resolvers
• Zero-config: reads credentials from ~/.memfork/credentials.json or MEMFORK_* env vars
