Add `clanker auth login/logout/status` commands for browser-based OpenAI OAuth PKCE flow. Tokens are stored at ~/.clanker/openai-auth.json. Add Codex Responses API client (internal/ai/codex_client.go) that sends requests to chatgpt.com/backend-api/codex/responses using OAuth tokens. When the OpenAI provider is selected but no API key is configured, the CLI checks for OAuth tokens and routes through the Codex client instead of the standard api.openai.com endpoint. Also support OPENAI_OAUTH_TOKEN env var for backend-forwarded tokens.
