Dmitriy Kovalenko bc13ff239c Add Bazel targets for on-demand schemas and Python SDK generation (#54096)
## What changed

- Add `//bazel/schema:app-server` to generate stable and experimental schemas from Rust sources without depending on committed precomputed bundles.
- Add `//sdk/python:generated` to generate Python SDK models, the notification registry, and API methods from the stable schema in scratch space, using dependencies from `uv.lock`.
- Add `generate-types --no-format` to skip formatters for build outputs while preserving formatting by default.

## Testing

Extend contract generation tests to regenerate in a temporary SDK copy, checking byte equality for formatted output and AST equality for unformatted output.

OpenAI Codex Python SDK

Build Python applications that start Codex threads, run turns, stream progress, and control workspace access.

Install

Install the SDK:

pip install openai-codex

Quickstart

The SDK reuses your existing Codex authentication when one is already available:

from openai_codex import Codex

with Codex() as codex:
    thread = codex.thread_start()
    result = thread.run("Explain this repository in three bullets.")
    print(result.final_response)

thread.run(...) returns a TurnResult containing the final response, collected items, and token usage.

Authentication

Existing Codex authentication is reused automatically. To start ChatGPT browser login explicitly:

from openai_codex import Codex

with Codex() as codex:
    login = codex.login_chatgpt()
    print(login.auth_url)
    print(login.wait().success)

For device-code login:

with Codex() as codex:
    login = codex.login_chatgpt_device_code()
    print(login.verification_url, login.user_code)
    login.wait()

For API-key login:

with Codex() as codex:
    codex.login_api_key("sk-...")

Built-In Help

Use Python's standard help(openai_codex), help(Codex), or python -m pydoc openai_codex documentation tools.
