Summary

• correct Agent/LangGraph lifecycle docs and generated API text to match the current lifecycle registry and reset behavior
• update streaming, interrupts, deployment, and installation guidance to match current agent() APIs and LangGraph interrupt patterns
• clarify subgraphs vs delegated subagents so docs do not imply subagents() tracks plain subgraph nodes

Verification

• npm run generate-api-docs
• git diff --check
• npx nx lint website (passes with existing warnings)
• npx nx test langgraph
• npx nx build website
• npx nx build langgraph
