fix(cli): defer parent agent env validation

Remove the root `CLAUDE.md` while retaining the shared `AGENTS.md`
instructions. No Claude-specific GitHub workflows are present, so
existing workflows remain unchanged.

-# AGENTS Instructions
-
-This repository is a monorepo. Each library lives in a subdirectory under `libs/`.
-
-<corridor>
-
-## Corridor security analysis
-
-Before generating or modifying code, create a plan and use Corridor's `analyzePlan` tool to analyze it. Apply the resulting security guidance before writing code.
-
-</corridor>
-
-When you modify code in any library, run the following commands in that library's directory before creating a pull request:
-
-- `make format` – run code formatters
-- `make lint` – run the linter
-- `make test` – execute the test suite
-
-To run a particular test file or to pass additional pytest options you can specify the `TEST` variable:
-
-```
-TEST=path/to/test.py make test
-```
-
-Other pytest arguments can also be supplied inside the `TEST` variable.
-
-## Libraries
-
-The repository contains several Python and JavaScript/TypeScript libraries.
-Below is a high-level overview:
-
-- **checkpoint** – base interfaces for LangGraph checkpointers.
-- **checkpoint-postgres** – Postgres implementation of the checkpoint saver.
-- **checkpoint-sqlite** – SQLite implementation of the checkpoint saver.
-- **cli** – official command-line interface for LangGraph.
-- **langgraph** – core framework for building stateful, multi-actor agents.
-- **prebuilt** – high-level APIs for creating and running agents and tools.
-- **sdk-js** – JS/TS SDK for interacting with the LangGraph REST API.
-- **sdk-py** – Python SDK for the LangGraph Server API.
-
-### Dependency map
-
-The diagram below lists downstream libraries for each production dependency as
-declared in that library's `pyproject.toml` (or `package.json`).
-
-```text
-checkpoint
-├── checkpoint-postgres
-├── checkpoint-sqlite
-├── prebuilt
-└── langgraph
-
-prebuilt
-└── langgraph
-
-sdk-py
-├── langgraph
-└── cli
-
-sdk-js (standalone)
-```
-
-Changes to a library may impact all of its dependents shown above.
-
-- Do NOT use Sphinx-style double backtick formatting (` ``code`` `). Use single backticks (`` `code` ``) for inline code references in docstrings and comments.

-# Jev browser agent with LangGraph and Stagehand
-
-This example rewrites the core idea behind [Jev Ultrafast](https://github.com/browser-use/jev-ultrafast) with:
-
-- the [LangGraph Functional API](https://docs.langchain.com/oss/python/langgraph/functional-api) for the bounded agent loop;
-- [`TypeSafeClassifier`](https://docs.langchain.com/oss/python/integrations/providers/typesafe) for Jev's typed, probabilistic decisions;
-- [Stagehand](https://docs.stagehand.dev/v4/reference/stagehand) for browser observation and deterministic actions;
-- a small LangChain chat model only when an action needs free-form text.
-
-Jev receives one shared state and answers speculative `Choice` questions for the next operation and compatible targets in parallel. The graph executes only the target head selected by the operation. Stagehand snapshot IDs are resolved to selectors by code, so model output never becomes arbitrary JavaScript or a free-form selector.
-
-## Run it
-
-```bash
-uv sync --all-groups
-export TYPESAFE_API_KEY=...
-export OPENAI_API_KEY=...
-uv run python agent.py \
-  'https://www.google.com/travel/flights?hl=en' \
-  'Find one-way flights from Zurich to London on September 20, 2026, for one adult in economy. Stop when matching flight options are visible.'
-```
-
-Use `--headed` to watch the run and `--max-steps` to lower the action budget. `TEXT_MODEL` defaults to `gpt-5.4-mini` and is called only for text-entry actions.
-
-Stagehand launches a fresh temporary Chrome profile by default. Keep it isolated: page content is sent to the configured model providers, and browser agents can make mistakes. The example stops instead of executing an action that Jev classifies as potentially sending, publishing, purchasing, deleting, or otherwise causing an irreversible side effect. Do not use it with credentials or sensitive pages without adding application-specific controls.
-
-## How it maps to LangGraph
-
-- `jev_browser_agent` is the `@entrypoint` and owns the action budget, browser lifecycle, and stop conditions.
-- `decide` is a `@task` that calls the LangChain TypeSafe integration.
-- `write_field_value` is a `@task` that uses a structured-output chat model because Jev makes decisions but does not generate strings.
-- Stagehand's `page.snapshot()` supplies the accessibility tree and the snapshot-ID-to-XPath map; `page.locator()` performs the selected action.
-
-This is an educational example, not a production browser security boundary. Production deployments should additionally restrict navigation domains, require human confirmation for consequential actions, redact traces, and independently verify completion.
