Some API proxies and gateways filter requests based on the User-Agent header (e.g. blocking the OpenAI SDK's default "OpenAI/Python ..."), which makes sgpt fail with PermissionDeniedError even though the same request succeeds via curl. Add an OPENAI_USER_AGENT config option (also available as an environment variable). When set to anything other than "default", it is passed to the OpenAI client via default_headers. The default value keeps the SDK's built-in User-Agent, so existing behavior is unchanged.

Motivation
Some API proxies and gateways filter requests by the
User-Agentheader. For example, a gateway may return403for any request whose UA matchesOpenAI/Python*— the OpenAI SDK's default — while the identical request body succeeds viacurl. In that case sgpt fails with:Since the OpenAI SDK provides no environment variable to override its
User-Agent, sgpt users behind such gateways currently have no workaround short of patching site-packages.Changes
OPENAI_USER_AGENTin~/.config/shell_gpt/.sgptrc(also usable as an environment variable, like other options)."default", which keeps the OpenAI SDK's built-inUser-Agent— behavior is unchanged for existing users.OpenAIclient viadefault_headers={"User-Agent": ...}(follows the same pattern asAPI_BASE_URL).Testing
