feat: add proxy support via child process spawning

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>

-
-This action relies on Node.js native proxy support.
-
-If you set `HTTP_PROXY` or `HTTPS_PROXY`, also set `NODE_USE_ENV_PROXY: "1"` on the action step so Node.js honors those variables. If you need proxy bypass rules, set `NO_PROXY` alongside them.
