release(cli): 0.4.39 (#9442 )

Bumps the CLI to 0.4.39 to cut a release including #9395, the only CLI change merged since 0.4.38: - `langgraph deploy list --json` prints `[{"id": "...", "name": "..."}]`, so a CI job can check whether a deployment exists before it deploys. - `deploy list` and `deploy listeners list` now read every page, instead of stopping at 20 deployments or 100 listeners. Merging doesn't publish by itself: after it merges, run the `release` workflow with `working-directory: libs/cli`.
docs: add "Direction: LangGraph is a runtime" section to AGENTS.md (#9439 )

+## Direction: LangGraph is a runtime
+
+LangGraph is consolidating as the low-level runtime for agents and workflows:
+graph execution, checkpointing, streaming, and interrupt/resume. Critical
+production systems and agent harnesses run on it, so correctness and stability
+come first. It is moving away from being a friendly SDK for building agents
+directly; agent development belongs one layer up, on a harness — Deep Agents
+(github.com/langchain-ai/deepagents, a separate repo) is the recommended one.
+
+Optimize contributions for runtime correctness, reliability, performance, and
+simplicity — not for the shortest agent example.
+
+- One way to do each thing. A change never adds a way; removals are always
+  deliberate (see below). The number of ways only goes down. No aliases,
+  overloads, extra accepted types, implicit defaults, or customization hooks
+  for convenience: ergonomics alone never justify new public surface.
+- The mandate applies to everything that implements runtime behavior, in
+  whichever repo it lives: the graph engine (`langgraph`, `langgraph-core`),
+  the checkpointers (`checkpoint*`), and the server (`langgraph-api`). The
+  client SDKs and CLI stay ergonomic but are thin, faithful clients, never a
+  second implementation of runtime behavior.
+- Agent-level packages (`prebuilt`, `langgraph-supervisor`, `langgraph-swarm`,
+  `langgraph-cua`) are maintenance-only: fix bugs, don't add agent features.
+  New examples and docs that build agents should use Deep Agents.
+- Remove deliberately, not opportunistically. Removing or changing public
+  behavior must be the stated purpose of the PR and go through the deprecation
+  process — replacement in place, removal version recorded, migration note.
+  Never drop a default or overload as a side effect of an unrelated change.
+- Behavior changes land in Python and JS together (the implementations live in
+  separate repos; note in the PR when the other one needs a matching change).
+- If a task asks for something this section rules out, say so and propose the
+  runtime-level or harness-level alternative instead of quietly implementing it.
+
 ## Libraries

 The repository contains several Python and JavaScript/TypeScript libraries.
