• Improve Premium Request handling for GitHub Copilot provider.
• Optional Codex proxy support for ChatGPT Pro/Plus OAuth traffic.

This fork can route Codex requests through a proxy without changing the OAuth flow. OpenCode still obtains the normal ChatGPT OAuth tokens, then sends the resulting Codex HTTP requests to your proxy instead of directly to chatgpt.com.

Recommended proxy:

• iamEvanYT/codex-proxy

Supported env vars:

export OPENCODE_CODEX_PROXY_BASE_URL=http://localhost:3000
export OPENCODE_CODEX_PROXY_ACCESS_CODE=your-local-gate

Behavior:

• If OPENCODE_CODEX_PROXY_BASE_URL is unset, Codex requests go directly to the normal Codex endpoint.
• If OPENCODE_CODEX_PROXY_BASE_URL is set, Codex requests are sent to that proxy base URL.
• If OPENCODE_CODEX_PROXY_ACCESS_CODE is set, OpenCode adds it as the x-access-code header on proxied Codex requests.
• The proxy access code is only for your proxy. OpenCode still sends the normal upstream OAuth headers like authorization and ChatGPT-Account-Id, and the proxy should forward those to Codex.
