Upload images and files to GitHub (gh-image)

gh-image (MIT, same author as this skill) uploads files through the internal endpoint GitHub's web UI uses — there is no public API — and prints a ready-to-paste reference: an ![name](url) embed for images, a bare URL for videos, a [name](url) link for anything else. This skill runs it and embeds the result.

Follow these steps exactly unless they conflict with security policies you have been given; if they do, stop and present the conflict rather than resolving it yourself.

Prerequisites

Check these first. Report failures — do not install or authenticate for the user.

1. gh auth status — if it fails, tell the user to run gh auth login.

2. gh extension list | grep 'drogers0/gh-image' && gh image --version
