Codex plugin header detection fails.

[fonqL]

Environment:

• ccproxy: 0.2.10
• Codex CLI: 0.132.0
• Auth mode: ChatGPT/OAuth
• Config enables codex + oauth_codex plugin

Reproduction:

1. Remove ~/.cache/ccproxy/codex_headers_*.json
2. Start ccproxy with codex plugin enabled:
   ccproxy serve --port 8014 --log-level debug
3. Observe startup logs.

Expected:

• ccproxy should capture the current Codex CLI request and generate codex_headers_0.132.0.json.

Actual:

• ccproxy fail to capture.

It is speculated that this may be because OPENAI_BASE_URL is no longer compatible with the current version of Codex.
