GitHub Copilot /chat/completions endpoint does not support the thinking
or reasoning_effort fields. OpenClaw sends thinking: { type: "enabled" }
for Claude models which causes a 400 Bad Request.
Added supportsThinking() and strip both fields in transformRequest before
sending to the upstream endpoint.
