codex-gateway v1.0.0

codex-gateway v1.0.0 is the first stable production release.
This release consolidates the beta cycle improvements into a reliable baseline, with stronger API compatibility, better network operability, and improved observability for real-world deployments.

Features & Enhancements / 功能与增强

• 🚀 Responses API support
  Added stable POST /v1/responses support in both upstream modes:
  • codex_oauth: proxies to configurable upstream.codex_responses_path
  • openai_api: proxies to configurable upstream.responses_path
    It supports both JSON and SSE pass-through.
• 🧠 Codex chat-compat tool parity
  Improved chat compatibility by mapping tool-related fields end to end, including tools, tool_choice, parallel_tool_calls, reasoning_effort, and tool_call_id.
  Tool-call semantics are now consistent in both streaming and non-streaming responses.
• 🌐 Outbound proxy support
  Introduced network.proxy_url with support for http, https, socks5, and socks5h.
  The proxy setting now applies consistently to both auth login and serve outbound traffic.
• 📊 Observability upgrades
  Enhanced structured logging (level, format, output, color, file rotation), added sensitive-field redaction, and improved request tracing with X-Request-ID propagation (preserve, generate, echo, and forward).
  Startup logging now includes api_prefix and discovered available_models to simplify operations and troubleshooting.
• 📚 Documentation and spec alignment
  Updated README, API reference, OpenAPI spec, OAuth setup, privacy boundary, and config examples (EN/zh-CN) to stay aligned with runtime behavior.

Compatibility Notes / 兼容性说明

• Existing OpenAI-compatible client integrations remain supported.
• In codex_oauth mode, compatibility fields such as max_output_tokens and max_completion_tokens are accepted but intentionally removed before upstream forwarding.
• Default upstream mode remains codex_oauth.
