Experimental: Codex Tool Support

Starting with this version, we have added a new experimental Codex extension (@openai/agents-extensions/experimental/codex). This extension allows you to use Codex as a tool within your agents. Since this module is still experimental, its behavior and implementation details may change in future releases.

If you run an agent with codexTool() on a host where Codex is installed, the agent will use Codex as a tool to answer the question. The tool simply runs the Codex CLI as a subprocess, so all existing Codex configuration, skills, and capabilities are available without any additional setup.

See the example code and #862 for more details.
