When proxy environment variables (https_proxy, HTTPS_PROXY, http_proxy, HTTP_PROXY) are detected and NODE_USE_ENV_PROXY is not already set to "1", the action spawns a child process with NODE_USE_ENV_PROXY=1 to enable Node.js native proxy support. - Add lib/run-with-proxy.js shared utility for both main.js and post.js - Update main.js and post.js to use runWithProxy() wrapper - Add tests for proxy spawning, child error handling, and already-enabled path - 100% code coverage maintained Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>
