Diagnose and self-heal an OpenClaw installation on Windows (gateway/service flapping, Feishu disconnects, browser CDP/headless issues, model auth 401/403/timeouts, Git conflicts/submodules, and GitHub push failures). Use when OpenClaw shows “Connection error”, frequent watchdog restarts, tool/API 401/404/429, “Invalid input[*].name … ^[a-zA-Z0-9_-]+$”, or when `git push` hangs/fails in `C:\Users\Administrator\.openclaw\workspace`.
