Function sync_codex_auth_from_codex_cli 

pub fn sync_codex_auth_from_codex_cli(
    cfg: &mut ProxyConfig,
    options: SyncCodexAuthFromCodexOptions,
) -> Result<SyncCodexAuthFromCodexReport, Error>

Sync Codex auth env vars from ~/.codex/config.toml + auth.json without changing routing config.

Default behavior:

• Only updates upstreams that are strongly associated with a Codex CLI provider:
  • config key equals provider_id; or
  • upstream.tags.provider_id equals provider_id.
• Does NOT change active / enabled / level unless options.set_active = true.
• Does NOT write secrets to disk; only syncs env var names (e.g. OPENAI_API_KEY).
